W3C also published xml:id document that allows the same use [XMLID] that is a recommendation. Currently, the WS-Policy specification does not use the xml:id mechanism for uniquely identifying XML elements and relies on the WSS definition of id mechanism. Justification: The purpose of the xml:id specification is to have unique element identifiers to be recognized by all conformant XML processors. Currently, WS-Policy relies on WS-Security specification for generating URI references instead and requires the framework providers to recognize this alternate mechanism for processing references. As xml:id will be adopted, the support of xml:id in all XML processors may require WS-Policy to also allow utilization of xml:id. Further, the specification does not clarify whether the xml:id is permissable as an identification mechanism for a WS-Policy expression. Target: Section 4.2 of the WS-Policy, Appendix A. Proposal: Allow xml:id as a permissible mechanism for identifying policy expressions in addition to wsu:Id 1. Replace {/wsp:Policy/@wsu:Id The identity of the policy expression as an ID within the enclosing XML document. If omitted, there is no implied value. To refer to this policy expression, a URI-reference MAY be formed using this value per Section 4.2 of WS-Security [WS-Security 2004].} With /wsp:Policy/{@wsu:Id | @xml:id} The identity of the policy expression as an ID within the enclosing XML document. If omitted, there is no implied value. To refer to this policy expression, a URI-reference MAY be formed using this value per Section 4.2 of WS-Security [WS-Security 2004] when @wsu:Id is used. 2. Repeat last example in Section 4.2 using xml:id in addition to wsu:id (last paragraph of Section 4.2) to illustrate the form. This is purely editorial. 3. Add normative reference to xml:id [XMLID] in A.1. Personal Note: I have chosen to retain the reference on wsu:Id given the expected schedule of the publication rather than removing it due to existing support on this attribute in the existing implementations. We could also add a note in the framework/primer when it is not desirable to use xml:id but rely on wsu:id if the wg feels that is necessary.

For example, a policy expression identified using xml:id attribute should not be signed using XML Digital Signature when Canonical XML 1.0 is being used as the canonicalization method."
