I believe that the intent of this document is that it be a "registry" (of
of normatively defined MEPs. They need not be defined in W3C specs
necessarily, but they do need to be formally defined/specified (IMO).

The Usage Scenarios doc [1] would be where I would expect to find a
list of patterns (MEPs) required for Web services at a higher level of
abstraction (e.g. not a formal specification).

             May I suggest that this document be the reference which
THE collection of all MEPs required for web services (and SOAP message
based) interactions ? Currently the "defined message exchange patterns"
contain only the interactions defined in a W3C specification.

             A related question : Should we have a registration process for
MEPs ? Then all specifications - W3C/OASIS et al - can uniformly and
unambiguously refer to MEPs.

|  Subject: Message exchange patterns document
|  As per my action item, I have started a document about message
|  exchange patterns whose goals are (from the abstract):
|       * explain how to document a MEP.
|       * list the MEPs developed within the Web Services Activity.
|       * eliminate discrepancies.
|  The document is available at:

Message exchange patterns have a role in SOAP, WSDL, and are likely to
come to play in other places (e.g. conversation, choreography).

I think that the XML Protocol Working Group and the Web Services
Description Working Group should come in agreement about using a same
concept and way to describe MEPs, and that the Web Services
Architecture Working Group should look into generalizing MEPs.
