I won't be at the f2f but my main purpose in this group is to get a
recommendation on what the addressing folks should do, so I'm fine with
this being discussed at the f2f.

Well, someone has to say this if we want implementers to follow your
suggestion. It can't certainly be WSDL and we can expect the developers
to read this mailing list before implementing the spec. Doing nothing
will only lead to confusion. It ought to be documented in the policy
specs, probably in the WSDL part of the attachment spec. Besides your
suggestion, we can say:
- don't mix WSDL extensions and WS-Policy, ie if your extension has a
corresponding policy assertion, then you should only use the policy
assertion if Policy is engaged.
- ignore all WSDL extensions when Policy is engaged.

The inconvenient of the last approach is of course the limitation
introduced in the Web services stack, which would force us to bend
Policy later on to use extensions that don't necessarily have a place
there.
