Proposal for issue 3620

Here is an outline proposal for issue 3620.  This proposal resolves the
issue by inserting the following as the new section 5 of the Policy
Attachments spec, in between WSDL and UDDI.  The new section covers
guidelines for interoperably attaching WS-Policies to WSA EPRs, and
typical rules for interpreting them.

This proposal does not include actual full-fidelity spec text, but it
makes clear the jist of the section and can be fleshed out by volunteers
or by the editors as appropriate.

I think this is important to include in our spec, and I don't believe
resolving the issue needs to be a lot of work, or a whole lot of
verbiage.

Thanks, (proposal follows)

5. Attaching Policies Using Endpoint References

- description of EPRs, their metadata section, and intent for policy
therein
- reference to WSA spec

5.1  Syntax

- The RECOMMENDED way to attach policy to an EPR is as a top-level child
of the <wsa:Metadata> element.
- Examples

5.2  Interpretation and Usage

- When policy is attached to an EPR, the policy refers to the Endpoint
Subject as described in 4.1.2.  [this is really the most important point
IMO]

- Description of precedence rules, and coverage of lifecycle issues (we
explain typical use-cases such as receiving a new policy-laden EPR for a
peer in the midst of a conversation, but do not mandate any particular
rules which MUST be followed always)
