1. Introduction

This document defines the WS-I Attachments Profile 1.0 (hereafter, "Profile"), consisting of a set of non-proprietary Web services specifications, along with clarifications to and amplifications of those specifications that are intended to promote interoperability. This profile compliments the WS-I Basic Profile 1.1 to add support for conveying interoperable SOAP Messages with Attachments-based attachments with SOAP messages.

SOAP Messages with Attachments (SwA) defines a MIME multipart/related structure for packaging attachments with SOAP messages. This profile complements the WS-I Basic Profile 1.1 to add support for conveying interoperable SwA-based attachments with SOAP messages.

Section 1 introduces the Profile, and explains its relationships to other profiles.

Section 2, "Profile Conformance," explains what it means to be conformant to the Profile.

Each subsequent section addresses a component of the Profile, and consists of two parts; an overview detailing the component specifications and their extensibility points, followed by subsections that address individual parts of the component specifications.

1.1 Relationship to other Profiles

This Profile adds support for SOAP with Attachments and MIME bindings, and is intended to be used in combination with the Basic Profile 1.1.

1.2 Notational Conventions

The keywords "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC2119.

Normative statements of requirements in the Profile (i.e., those impacting conformance, as outlined in "Conformance Requirements") are presented in the following manner:

where "nnnn" is replaced by a number that is unique among the requirements in the Profile, thereby forming a unique requirement identifier.

Requirement identifiers can be considered to be namespace qualified, in such a way as to be compatible with QNames from Namespaces in XML. If there is no explicit namespace prefix on a requirement's identifier (e.g., "R9999" as opposed to "bp10:R9999"), it should be interpreted as being in the namespace identified by the conformance URI of the document section it occurs in. If it is qualified, the prefix should be interpreted according to the namespace mappings in effect, as documented below.

Some requirements clarify the referenced specification(s), but do not place additional constraints upon implementations. For convenience, clarifications are annotated in the following manner: C

Some requirements are derived from ongoing standardization work on the referenced specification(s). For convenience, such forward-derived statements are annotated in the following manner: xxxx, where "xxxx" is an identifier for the specification (e.g., "WSDL20" for WSDL Version 2.0). Note that because such work was not complete when this document was published, the specification that the requirement is derived from may change; this information is included only as a convenience to implementers.

Extensibility points in underlying specifications (see "Conformance Scope") are presented in a similar manner:

where "nnnn" is replaced by a number that is unique among the extensibility points in the Profile. As with requirement statements, extensibility statements can be considered namespace-qualified.

This specification uses a number of namespace prefixes throughout; their associated URIs are listed below. Note that the choice of any namespace prefix is arbitrary and not semantically significant.

1.3 Profile Identification and Versioning

This document is identified by a name (in this case, Attachments Profile) and a version number (here, 1.0). Together, they identify a particular profile instance.

Version numbers are composed of a major and minor portion, in the form "major.minor". They can be used to determine the precedence of a profile instance; a higher version number (considering both the major and minor components) indicates that an instance is more recent, and therefore supersedes earlier instances.

Instances of profiles with the same name (e.g., "Example Profile 1.1" and "Example Profile 5.0") address interoperability problems in the same general scope (although some developments may require the exact scope of a profile to change between instances).

One can also use this information to determine whether two instances of a profile are backwards-compatible; that is, whether one can assume that conformance to an earlier profile instance implies conformance to a later one. Profile instances with the same name and major version number (e.g., "Example Profile 1.0" and "Example Profile 1.1") MAY be considered compatible. Note that this does not imply anything about compatibility in the other direction; that is, one cannot assume that conformance with a later profile instance implies conformance to an earlier one.

2 Profile Conformance

Conformance to the Profile is defined by adherence to the set of requirements defined for a specific target, within the scope of the Profile. This section explains these terms and describes how conformance is defined and used.

2.1 Conformance Requirements

Requirements state the criteria for conformance to the Profile. They typically refer to an existing specification and embody refinements, amplifications, interpretations and clarifications to it in order to improve interoperability. All requirements in the Profile are considered normative, and those in the specifications it references that are in-scope (see "Conformance Scope") should likewise be considered normative. When requirements in the Profile and its referenced specifications contradict each other, the Profile's requirements take precedence for purposes of Profile conformance.

Requirement levels, using RFC2119 language (e.g., MUST, MAY, SHOULD) indicate the nature of the requirement and its impact on conformance. Each requirement is individually identified (e.g., R9999) for convenience.

This requirement is identified by "R9999", applies to the target WIDGET (see below), and places a conditional requirement upon widgets; i.e., although this requirement must be met to maintain conformance in most cases, there are some situations where there may be valid reasons for it not being met (which are explained in the requirement itself, or in its accompanying text).

Each requirement statement contains exactly one requirement level keyword (e.g., "MUST") and one conformance target keyword (e.g., "MESSAGE"). The conformance target keyword appears in bold text (e.g. "MESSAGE"). Other conformance targets appearing in non-bold text are being used strictly for their definition and NOT as a conformance target. Additional text may be included to illuminate a requirement or group of requirements (e.g., rationale and examples); however, prose surrounding requirement statements must not be considered in determining conformance.

Definitions of terms in the Profile are considered authoritative for the purposes of determining conformance.

None of the requirements in the Profile, regardless of their conformance level, should be interpreted as limiting the ability of an otherwise conforming implementation to apply security countermeasures in response to a real or perceived threat (e.g., a denial of service attack).

2.2 Conformance Targets

Conformance targets identify what artifacts (e.g., SOAP message, WSDL description, UDDI registry data) or parties (e.g., SOAP processor, end user) requirements apply to.

This allows for the definition of conformance in different contexts, to assure unambiguous interpretation of the applicability of requirements, and to allow conformance testing of artifacts (e.g., SOAP messages and WSDL descriptions) and the behavior of various parties to a Web service (e.g., clients and service instances).

Requirements' conformance targets are physical artifacts wherever possible, to simplify testing and avoid ambiguity.

2.3 Conformance Scope

The scope of the Profile delineates the technologies that it addresses; in other words, the Profile only attempts to improve interoperability within its own scope. Generally, the Profile's scope is bounded by the specifications referenced by it.

The Profile's scope is further refined by extensibility points. Referenced specifications often provide extension mechanisms and unspecified or open-ended configuration parameters; when identified in the Profile as an extensibility point, such a mechanism or parameter is outside the scope of the Profile, and its use or non-use is not relevant to conformance.

Note that the Profile may still place requirements on the use of an extensibility point. Also, specific uses of extensibility points may be further restricted by other profiles, to improve interoperability when used in conjunction with the Profile.

Because the use of extensibility points may impair interoperability, their use should be negotiated or documented in some fashion by the parties to a Web service; for example, this could take the form of an out-of-band agreement.

The Profile's scope is defined by the referenced specifications in Appendix A, as refined by the extensibility points in Appendix B.

2.4 Claiming Conformance

Claims of conformance to the Profile can be made using the following mechanisms, as described in Conformance Claim Attachment Mechanisms, when the applicable Profile requirements associated with the listed targets have been met:

The conformance claim URI for this Profile is "http://ws-i.org/profiles/attachments/1.0" .

3. Attachments Packaging

This section of the Profile incorporates the following specifications by reference, and defines extensibility points within them:

SOAP Messages with Attachments defines a MIME multipart/related structure for packaging SOAP envelope with attachments. The Profile mandates the use of that structure, and places the following constraints on its use:

3.1 Root Part

R2931 The entity body of the root part of multipart/related MESSAGE MUST be a soap:Envelope.

R2945 The Content-Type HTTP header field-value in a MESSAGE MUST be either "multipart/related" or "text/xml". C

R2932 If the Content-Type HTTP header field-value in a MESSAGE has a media-type of "multipart/related" then the Content-Type HTTP header field-value in that message MUST have the type parameter with a value of "text/xml". C

Any MIME part may contain a soap:Envelope, but only the entity body of the root-part of the MIME package is treated as the primary SOAP envelope. Non-root parts are referred to as attachments.

CORRECT:

In the message below the the Content-Type HTTP header field-value has a media-type of 'Multipart/Related' and a parameter 'type' with value of 'text/xml'.

MIME-Version: 1.0
Content-Type: Multipart/Related; boundary=MIME_boundary; type=text/xml;
Content-Description: This is the optional message description.

--MIME_boundary
Content-Type: text/xml; charset=UTF-8
Content-Transfer-Encoding: 8bit
Content-ID: <rootpart@example.com>

<?xml version='1.0' ?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
...
</SOAP-ENV:Envelope>

--MIME_boundary

...
--MIME_boundary--

3.2 Encoding of Root Part

R2915 The entity body of the root part of a multipart/related MESSAGE MUST be serialized using either UTF-8 or UTF-16 character encoding.

R2916 Non-root parts of a multipart/related MESSAGE MAY use any character encoding.

3.3 Media Type of Message

R2925 If the WSDL description lists at least one non-root MIME part, the corresponding MESSAGE MUST have a Content-Type HTTP header field-value with a media-type of "multipart/related".

3.4 Messages with No Attachments

If a receiver expects zero or more attachments in a message, the sender of that message can use the text/xml media type for a message that has no attachments.

R2917 A MESSAGE containing zero attachment parts MUST be sent using a content-type of either "text/xml" as though a SOAP HTTP binding were used or "multipart/related" when the WSDL description for the message specifies the mime:multipartRelated element on the corresponding wsdl:input or wsdl:output element in its wsdl:binding.

R2902 A SENDER MUST NOT send a message using SOAP with Attachments if the corresponding wsdl:inputor wsdl:output element in the wsdl:binding does not specify the WSDL MIME Binding.

This can happen only when the WSDL description specifies a mime:multipartRelated that has only one mime:part child element containing soapbind:body.

CORRECT:

A WSDL Description that is as follows:

<wsdl:definitions xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
                  xmlns:soapbind="http://schemas.xmlsoap.org/wsdl/soap/"
                  xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
                  xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/" 
                  targetNamespace="http://example.com/mimewsdl"
                  xmlns:tns="http://example.com/mimewsdl">

...

    <wsdl:binding name="aBinding" type="tns:aPortType">
        <soapbind:binding style="rpc" 
                          transport="http://schemas.xmlsoap.org/soap/http"/>
        <wsdl:operation name="anOperation">
            <soap:operation soapAction="http://example.com/soapaction"/>
            <wsdl:input>
                <mime:multipartRelated>
                    <mime:part>
                        <soapbind:body use="literal" 
                                       namespace="http://example.com/mimetypes"/>
                    </mime:part>
                </mime:multipartRelated>
            </wsdl:input>
            <wsdl:output>
                <soapbind:body use="literal" 
                               namespace="http://example.com/mimetypes"/>
            </wsdl:output>
        </wsdl:operation>
 </wsdl:binding>
</wsdl:definitions>

may result in an input message which uses the SOAP HTTP Binding as follows:

<?xml version='1.0' ?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
    <SOAP-ENV:Body xmlns:types="http://example.com/mimetypes">
        <types:anOperation>
 ...
         </types:anOperation>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

must not result in an output message which uses the MIME Binding as follows:

MIME-Version: 1.0
Content-Type: Multipart/Related; boundary=MIME_boundary; type=text/xml;
        start="<rootpart@example.com>"
Content-Description: This is the optional message description.

--MIME_boundary
Content-Type: text/xml; charset=UTF-8
Content-Transfer-Encoding: 8bit
Content-ID: <rootpart@example.com>

<?xml version='1.0' ?>
<SOAP-ENV:Envelope 
 xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
    <SOAP-ENV:Body xmlns:types="http://example.com/mimetypes">
        <types:anOperationResponse>
...
        </types:anOpertionResponse>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

--MIME_boundary--

3.5 Dereferencing Attachments

Applications using Web services can use URIs in a variety of ways, including as a means of fetching content from a network. Although attachments can be used to provide content which is identified with a URI, implementations are not required to prefer attached content, to use it exclusively, or to use it at all. Likewise, applications may choose to ignore the specified dereference function of a URI (e.g., fetching content from a network) and only use attached content.

When using the CID URI scheme, the syntax and rules defined in RFC 2392 apply.

R2918 A RECEIVER MAY ignore a URI reference to an attachment in an envelope.

3.6 Carrying Additional SOAP Envelopes

The Profile places no constraints on the content of attachment parts. Additional XML documents that contain a soap:Envelope may be sent as attachments, but only the root-part of the MIME message should be treated as the primary soap envelope in a MIME package.

R2919 A MESSAGE MAY contain soap:Envelopes carried as attachments in parts that are not the root part of the message.

3.7 Fault Messages with Attachments

R2920 An INSTANCE MAY send a fault with attachments if and only if the wsdl:output element is described using the WSDL MIME binding.

3.8 Value-space of Content-Id Header

Definition: content-id part encoding

The "content-id part encoding" consists of the concatenation of:

The value of the name attribute of the wsdl:part element referenced by the mime:content, in which characters disallowed in content-id headers (non-ASCII characters as represented by code points above 0x7F) are escaped as follows:
- Each disallowed character is converted to UTF-8 as one or more bytes.
- Any bytes corresponding to a disallowed character are escaped with the URI escaping mechanism (that is, converted to %HH, where HH is the hexadecimal notation of the byte value).
- The original character is replaced by the resulting character sequence.
The character '=' (0x3D).
A globally unique value such as a UUID.
The character '@' (0x40).
A valid domain name under the authority of the entity constructing the message.

R2933 If a description binds a wsdl:message part to a mime:content element, then the corresponding MIME part's content-id field-value in a MESSAGE MUST conform to the content-id part encoding.

CORRECT:

In the WSDL fragment below, the name of the part bound to the mime:content is the value appended to the content-id value.


<wsdl:message name="fooMsg">
  <wsdl:part name="body" type="ns1:Claim"/>
  <wsdl:part name="fooPart" type="xs:base64binary"/>
</wsdl:message>
...
<wsdl:binding
    ...
    <mime:multipartRelated>
      <mime:part>
        <soapbind:body parts="body" use="literal"/>
      </mime:part>
      <mime:part>
        <mime:content part="fooPart" type="application/octet-stream"/>
      </mime:part>
    </mime:multipartRelated>
    ...
</wsdl:binding>

Here's a fragment of the multipart package containing the fooPart binary stream highlighting how the "name" attribute of wsdl:part is incorporated into the content-id value.


...
--MIME_boundary
Content-Type: application/octet-stream
Content-Transfer-Encoding: 8bit
Content-ID: <fooPart=somereallybignumberlikeauuid@example.com>
...

3.9 Ordering of MIME Parts

It is possible that intermediaries might reorder the parts in a multipart/related message. Hence semantics should be neither given to, nor implied by the ordering of parts in a message.

R2921 A RECEIVER MUST NOT infer any semantics from the ordering of non-root MIME parts in a message.

R2929 A MESSAGE MAY have its MIME parts in any order provided that the identity of the root part is maintained.

A receiver must not assume that the order of mime:part elements specified in a WSDL description is the same as the order of MIME parts in the message. The order of MIME parts specified in a WSDL description must be considered independent of the order of MIME parts in the message.

3.10 Position of Root Part

If the start parameter is present, then the value of the start parameter is the content-ID of the root part of the message. In the absence of a start parameter, the root part is the first body part in the package, as defined by RFC 2387 Section 3.2.

R2922 If the Content-Type HTTP header field-value in a message does not have a start parameter, a RECEIVER MUST treat the first body part of the MIME package as the root part. C

CORRECT:

In the message below the first MIME part (which has the Content-ID header of "<rootpart@example.com>") is the root part.

MIME-Version: 1.0
Content-Type: Multipart/Related; boundary=MIME_boundary; type=text/xml;
Content-Description: This is the optional message description.

--MIME_boundary
Content-Type: text/xml; charset=UTF-8
Content-Transfer-Encoding: 8bit
Content-ID: <rootpart@example.com>

<?xml version='1.0' ?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
    <SOAP-ENV:Body xmlns:types="http://example.com/mimetypes">
        <types:SendClaim>
            <ClaimDetail>.............................</ClaimDetail>
            <photo>
              <href>cid:claimphoto@example.com</href>
            </photo>
        </types:SendClaim>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

--MIME_boundary
Content-Type: application/octet-stream
Content-Transfer-Encoding: binary
Content-ID: <claimphoto@example.com>

...binary photograph...
--MIME_boundary--

3.11 Content-Transfer-Encoding

Content-Transfer-Encodings allow messages to be sent across transports that do not support binary content; for example, some e-mail systems are only capable of transferring character-based messages. Because Web services messages may originate on or be destined for such systems, the Profile allows this mechanism's use.

If Content-Transfer-Encoding field of a part in mime multipart message is not present, the body of that part must conform to 7 bit ascii encoding as specified RFC 2045.

R2934 The Content-Transfer-Encoding field of a part in a multipart/related MESSAGE MUST have a value of "7bit", "8bit", "binary", "quoted-printable" or "base64".

R2935 The encoding of the body of a part in a multipart/related MESSAGE MUST conform to the encoding indicated by the Content-Transfer-Encoding field-value, as specified by RFC2045. C

The Profile restricts its legal values to those that are well-known to improve interoperability.

3.12 MIME Boundary String

Certain implementations have been shown to produce messages in which the MIME encapsulation boundary string is not preceded with a CRLF (carriage-return line-feed). This creates problems for implementations which correctly expect that the encapsulation boundary string is preceded by a CRLF.

R2936 In a MESSAGE, all MIME encapsulation boundary strings MUST be preceded with the ascii characters CR (13) and LF (10) in that sequence. C

RFC2046 section 5.5.1 clearly requires that all encapsulation boundaries must be preceded with a CRLF (carriage-return line-feed).

4. Attachments Description

This section of the Profile incorporates the following specifications by reference:

WSDL 1.1 section 5 defines the MIME binding. The Profile permits the use of the WSDL MIME binding, but limits it to the SOAP Messages with Attachments protocol. The Profile places the following constraints on its use:

4.1 Use of MIME Binding Extension

There may be use cases where a sender might be capable of sending a message using SOAP with Attachments yet incapable of receiving and processing such a message.

R2901 A DESCRIPTION MUST use either the WSDL MIME Binding as described in WSDL 1.1 Section 5 or WSDL SOAP binding as described in WSDL 1.1 Section 3 on each of the wsdl:input or wsdl:output elements of a wsdl:binding.

4.2 Unbound portType Element Contents

WSDL 1.1 is not explicit about whether it is permissible for a wsdl:binding to leave the binding for portions of the content defined by a wsdl:portType unspecified.

R2941 A wsdl:binding in a DESCRIPTION SHOULD bind every wsdl:part of a wsdl:message in the wsdl:portType to which it refers to one of soapbind:body, soapbind:header, soapbind:fault , soapbind:headerfault, or mime:content.

A portType defines an abstract contract with a named set of operations and associated abstract messages. Although not disallowed, it is expected that every part of the abstract input, output and fault messages specified in a portType is bound to soapbind:body or soapbind:header (and so forth) or a mime:content as appropriate when using the MIME binding as defined in WSDL 1.1 Section 5. Un-bound wsdl:parts should be ignored by a consumer.

4.3 Referencing Message Parts

A message part in WSDL can be bound to a particular MIME part (using mime:content).Unlike a soapbind:header which may reference parts contained in a message that is not part of the contract defined by the wsdl:porttype, a mime:content must not reference a wsdl:part that is not defined in the wsdl:message referenced by the wsdl:operation. Additionally, message parts in WSDL are considered to be an indivisible unit. Components of a message part which is of complex content cannot be selectively bound to a particular MIME part.

R2903 A mime:content element in a DESCRIPTION MUST NOT reference a wsdl:part that is not present in the respective wsdl:input or wsdl:output of the corresponding wsdl:operation of the corresponding wsdl:portType.

R2904 A mime:content element in a DESCRIPTION MUST NOT be bound to a sub-component of an element or type referenced by a wsdl:part.

R2946 In a DESCRIPTION, a mime:content element MUST include the part attribute.

INCORRECT:

<definitions xmlns="http://schemas.xmlsoap.org/wsdl/"> 
  <types ...> 
    <schema xmlns="http://www.w3.org/2001/XMLSchema/" 
            targetNamespace="http://example.org/foo"

        </mime:part>
      </mime:multipartRelated>
    </input>

  </operation>
</binding>
</definitions>

4.4 Referencing Attachments from the SOAP Envelope

One of the advantages of having attachments is the ability to include data in a separate MIME part and refer to it from the SOAP envelope contained in the root part of the same MIME package.

This Profile defines a schema type ref:swaRef which can be used in a WSDL description to define a message part. When a message part is described using the ref:swaRef type, in its instance document, the URI points to an attachment in the same MIME package. This type is offered to application/tool/platform developers as an interoperable way to mark references to attachments in the descriptions. Nevertheless, use of other mechanisms does not make the description non-conformant.

The XML Schema for the type used to refer to attachments from the SOAP envelope is:


<?xml version="1.0" encoding="UTF-8" ?> 
<xsd:schema targetNamespace="http://ws-i.org/profiles/basic/1.1/xsd" 
            xmlns:xsd="http://www.w3.org/2001/XMLSchema"> 
  <xsd:simpleType name="swaRef"> 
    <xsd:restriction base="xsd:anyURI" /> 
  </xsd:simpleType> 
</xsd:schema>

As a convenience, WS-I has published the schema for this schema type at: http://ws-i.org/profiles/basic/1.1/swaref.xsd

Please note that there is no way in a WSDL1.1 description to correlate an attachment reference (defined using swaRef) with an attachment (defined using a wsdl:part bound to mime:content). As a best practice, the Profile recommends that when ref:swaRef is used, the corresponding attachment should not be described, and vice versa.

R2940 In a DESCRIPTION, a wsdl:part defined with the ref:swaRef schema type SHOULD only be bound to a soapbind:body, or a soapbind:header in a MIME binding.

R2928 In an ENVELOPE, a URI reference that is typed using the ref:swaRef schema type MUST resolve to a MIME part in the same message as the envelope.

The swaRef type can be used to represent a reference to an attachment either as an element (as shown in the example below) or an attribute. There is no preferred approach.

4.5 Specifying Root Part

SOAP Messages with Attachments requires that the root part of the multipart/related package must contain the SOAP envelope, but the WSDL MIME binding is unclear on how this is described.

R2911 A mime:multipartRelated element in a DESCRIPTION MUST contain exactly one mime:part element, amongst its child mime:part elements, containing a soapbind:body child. C

In a WSDL MIME binding, the mime:part that contains a soapbind:body describes the root MIME part required by SOAP Messages with Attachments.

INCORRECT:

</wsdl:definitions>

4.6 Specifying SOAP Headers in Root Part

The WSDL1.1 specification does not specify whether the soapbind:header element is permitted as a child of the mime:part element along with the soapbind:body element. The SOAP Messages with Attachments specification requires that the root part of the multipart message contain the SOAP envelope, but the WSDL1.1 specification is unclear as to how to describe this part. Since the WSDL1.1 specification specifies that the mime:part element is used to describe each part of a multipart/related message, the contents of the mime:part element that represents the root part of the multipart message must therefore fully describe the SOAP envelope, including the soapbind:body and soapbind:header elements just as they would be used in the absence of the WSDL MIME binding extension.

R2905 The soapbind:header element in a DESCRIPTION MAY be included as a child of the mime:part element. C

R2906 A soapbind:header element in a DESCRIPTION MUST NOT be included in a mime:part that is not the root part, containing the soapbind:body element. C

INCORRECT:

4.7 MIME Binding Schema Fixes

There are a number of discrepancies between the WSDL1.1 specification and the WSDL MIME binding schema. In the case of the mime:part element, the schema incorrectly defines it as a local element declaration and it incorrectly adds a name attribute that is not described in the WSDL1.1 specification.

These and other fixes to the WSDL MIME Binding extension schema are reflected in the revised schema located at "http://ws-i.org/profiles/basic/1.1/wsdlmime-2004-08-24.xsd".

R2907 MIME parts in a DESCRIPTION MUST be defined using an element with a local name of part in the namespace of the WSDL MIME Binding extension. C

R2908 The mime:part element in a DESCRIPTION MUST NOT have a name attribute.

4.8 Specifying Alternate Media Types

Multiple mime:content element children of a mime:part are considered alternate acceptable serializations of the referenced wsdl:part.

R2909 Multiple mime:content child elements of a mime:part element in a DESCRIPTION MUST reference the same wsdl:part.

INCORRECT:

<mime:part>
  <mime:content part="ns:foo" type="image/jpeg"/>
  <mime:content part="ns:bar" type="image/jpeg"/>
</mime:part>

CORRECT:

<mime:part>
  <mime:content part="ns:foo" type="image/jpeg"/>
  <mime:content part="ns:foo" type="image/gif"/>
</mime:part>

4.9 WSDL Parts

R2910 A mime:content in a DESCRIPTION MUST reference a wsdl:part that is defined using either the type attribute or the element attribute.

R2942 In a MESSAGE, a message part bound to a mime:content that refers to global element declaration (via the element attribute of the wsdl:part element) MUST be serialized within the MIME part as a serialization of an XML infoset whose root element is described by the referenced element.

R2943 In a DESCRIPTION, if a message part is bound to a mime:content that refers to a type (via the type attribute of the wsdl:part element), then the value of that type attribute MUST be ignored in favor of media type of the type attribute of the mime:content element.

R2944 In a DESCRIPTION, if a wsdl:part element refers to a global element declaration (via the element attribute of the wsdl:part element) then the value of the type attribute of a mime:content element that binds that part MUST be a content type suitable for carrying an XML serialization.

4.10 Ordering of Parts

R2912 A RECEIVER MUST NOT assume that the order of mime:part elements specified in a WSDL description is the same as the order of MIME parts in the message.

R2947 In a DESRIPTION, a mime:part element that contains a soapbind:body child element MAY appear in any position amongst the other child elements of a mime:multipartRelated element.

The order of MIME parts specified in a WSDL description must be considered independent of the order of MIME parts in the message.

4.11 Sending Fault Messages

R2913 A Fault MESSAGE MAY be serialized as either text/xml or multipart/related, if the wsdl:output child element of the corresponding binding operation in a description has a child mime:multipartRelated element.

4.12 Describing Faults

R2930 A wsdl:fault element in a DESCRIPTION MUST NOT have mime:multipartRelated element as its child element.

4.13 Sending Additional Parts Not Described in WSDL

Additional MIME parts may be included in the message beyond those described in the WSDL, and their position or order within the MIME package is not important.

R2923 A SENDER MAY send non-root MIME parts not described in the WSDL MIME binding. C

R2926 A MESSAGE MUST include all of the MIME parts described by its WSDL MIME binding.

4.14 Conformance of SOAP Messages

Profile conformance criteria for the conformance target ENVELOPE only apply to the SOAP envelope contained in the root part of the MIME package. SOAP envelopes in non-root parts may be described in a WSDL description as attachments, in which case, conformance criteria for non-root parts listed in the WSDL description apply.

R2927 The root part of a MESSAGE MUST be conformant with all the requirements for an envelope in version 1.1 of the Basic Profile.

4.15 Example Attachment Description Using mime:conent

CORRECT:
