To allow advertisement of profile conformance, artifacts can be annotated with conformance claims, which use URIs to assert that a particular claim subject (e.g., an artifact or a party to a Web service) meets the appropriate requirements in the indicated profile.
The requirements considered in-scope for a particular conformance claim are those placed upon the conformance target(s) associated with the claim attachment mechanism by the relevant profile.
Therefore, every profile specifies its own conformance claim URI. Furthermore, every profile documents which of its conformance targets are in-scope for each claim attachment mechanism described in the following sections.
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.
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.
Conformance claims can be attached to a wsdl:port
element in a WSDL 1.1 description as a child of its
wsdl:documentation element,
using the Conformance Claim Schema (see "Conformance Claim XML Schema").
Such conformance claims indicate that the associated Web service instance exhibits conformant behavior, as determined by the requirements associated with this attachment mechanism by the referenced profile.
A conformance claim attached to a wsdl:port element also indicates that it itself is a conformant XML construct. Additionally, the same claim is made for all elements recursively referenced by it, based on the transitivity rules described in "WSDL 1.1 Claim Attachment Mechanism for Description Constructs."

Conformance claims can be attached to wsdl:binding,
wsdl:portType, wsdl:operation (as a child
element of wsdl:portType, but not of
wsdl:binding) and wsdl:message elements in a
WSDL 1.1 description, using the Conformance Claim Schema (see "Conformance Claim XML Schema").
A conformance claim attached to any of these elements indicates that it is a conformant XML construct, as determined by the requirements associated with this attachment mechanism by the referenced profile. Additionally, the same claim is made for all elements that it references, based on the following transitivity rules, applied recursively:
wsdl:port element is inherited by the
referenced wsdl:binding elementwsdl:binding element is inherited by the
referenced wsdl:portType elementwsdl:portType element is inherited by the
referenced wsdl:operation elementswsdl:operation element is inherited by the
referenced wsdl:message elements of its child
wsdl:output and/or wsdl:input
elementsConformance claims can be attached to a uddi:tModel in a
UDDI Version 2 or 3 registry using the appropriate
ws-i-org:conformsTo:2002_12 category system tModel (see
"Conformance Claim tModels").
A conformance claim attached to a tModel indicates that it is a conformant XML construct, as determined by the requirements associated with this attachment mechanism by the referenced profile.
uddi:tModels should be constructed so that the
conformance claims placed upon them are consistent with the conformance claims
made by the wsdl:bindings to which they refer.
The categorization value should correspond to the conformance claim URI for the profile.

</tModel>
Here, the tModel with the name "BarSOAPService" claims to conform to the
Basic Profile 1.0, as indicated by the keyedReference – the tModelKey
references the ws-i-org:conformsTo:2002_12 category system
and the keyValue identifies the conformance claim URI for the Basic Profile
1.0.
In UDDI Version 2 registries, uddi:bindingTemplate
elements can't be categorized because the UDDI Version 2 XML Schema does not
provide a uddi:categoryBag for them. Hence, the conformance
claim made by wsdl:port elements can't be documented in their
corresponding UDDI Version 2 uddi:bindingTemplates.
Conformance claims can be attached to a
uddi:bindingTemplate in a UDDI Version 3 registry using the
ws-i-org:conformsTo:2002_12 category system tModel specified
in Section 4.2. Note that this attachment mechanism is not available in UDDI
Version 2 registries.
Such conformance claims indicate that the associated Web service instance exhibits conformant behavior, as determined by the requirements associated with this attachment mechanism by the referenced profile.
A conformance claim attached to a uddi:bindingTemplate
also indicates that the tModel itself is a conformant registry contruct.
Additionally, a claim made for a uddi:bindingTemplate is made
for all tModels it references.

Since UDDI Version 3 allows the categorization of
uddi:bindingTemplates, It would be ambiguous if the
conformance claim a uddi:bindingTemplate made were not
consistent with the claim made by the wsdl:port it
represents, when used in combination with a WSDL 1.1 description. Therefore,
uddi:bindingTemplates must be constructed so that the
conformance claims they make are consistent with any
wsdl:ports that they refer to.

When possible (i.e., when a claim attachment is made in an extensible XML document), conformance claims SHOULD be made with an Element Information Item conformant to the following XML Schema:
<?xml version="1.0" encoding="UTF-8" ?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
targetNamespace="http://ws-i.org/schemas/conformanceClaim/"
xmlns:tns="http://ws-i.org/schemas/conformanceClaim/"

<xsd:attribute ref="soap:mustUnderstand" use="prohibited" />
<xsd:anyAttribute namespace="##any" processContents="lax" />
</xsd:complexType>
</xsd:element>
</xsd:schema>>
The Claim element has a mandatory conformsTo attribute, whose value contains the actual conformance claim URI. The conformance claim schema explicitly allows for extensibility elements and attributes.

The Version 3 tModelKey for the
ws-i-org:conformsTo:2002_12 tModel is
"uddi:65719168-72c6-3f29-8c20-62defb0961c0". In a multi-version registry this
results in the correct Version 2 key allowing conformance claims work
correctly across versions.
