The example in Section 3.4 WS-PolicyAttachment [1] is illustrative. It
illustrates an extensibility point in the external policy attachment.

Here is what I see in the draft on this question:

"For the purposes of attaching policy to a policy subject through this
mechanism, any policy expression contained inside of the wsp:AppliesTo
element MUST NOT be considered in scope. For example, an Endpoint
Reference may be used as a domain expression, and it may contain policy
expressions within it, but this policy expressions are not considered in
scope with respect to the wsp:PolicyAttachment element using it."

I hope this helps.

Subject: Issue 3619 - input from WS-Addressing WG


Add an issue on coordination with other working groups
http://www.w3.org/Bugs/Public/show_bug.cgi?id=3619

Maryann carried out her action to ask the WS-Addressing WG to review the
example in Section 3.4 of WS-PolicyAttachments:
http://lists.w3.org/Archives/Public/public-ws-addressing/2006Aug/0087.ht
ml

We need to consider the questions asked by Marc Hadley in his response
to Maryann's request:
http://lists.w3.org/Archives/Public/public-ws-addressing/2006Aug/0089.ht
ml

"Have you considered the semantics when other things are included in
the EndpointReference. In particular, if the EPR contains a metadata
element with an embedded wsp:Policy (either directly or via an
intermediate embedded or referenced WSDL), how are the policies
reconciled?"

WG members are encouraged to reply to this thread to help the WG to
reach consensus on how to reply to Marc's question.
