RE: issue 7728: point 1 - proposal for indicating effective endpoint policy in an EPR

The underlying use case is addressed by a general-purpose, existing feature [1][2] in the current WS-MetadataExchange draft. For example,

<wsa:EndpointReference>
  <wsa:Address>http://services.example.org/stockquote</wsa:Address>
  <wsa:Metadata>
   <mex:Metadata>
    <mex:MetadataSection>
      Dialect='http://www.w3.org/ns/ws-policy'>
     <wsp:Policy> ... </wsp:Policy>
    </mex:MetadataSection>
   </mex:Metadata>
  </wsa:Metadata>
</wsa:EndpointReference>

Adobe, IBM, Microsoft, Oracle, Sun and WSO2 interop tested [3][4] the feature in April 2007.

Has anyone analyzed why the existing feature does not address the underlying use case?

Subject: issue 7728: point 1 - proposal for indicating effective endpoint policy in an EPR

I've attached the first draft of our proposal for incorporating WS-PAEPR into WS-Mex [1] to the entry for issue 7728. This is accomplished by creating a new section, Section 7.2, that describes what it means to put a wsp:Policy or wsp:PolicyReference in a wsa:EndpointReference/wsa:Metadata element.

Note this addresses the WS-DD comments ([2], [3]) made on WS-MetadataExchange by Antoine Mensch.
