The WSCG, during yesterday's telcon[1], discussed the problem of MEP
definition coordination.

The Web Services Description Working Group must be able to use the
MEPs defined by XML Protocol Working Group, and basically not redefine

It seems that for the time being, the Web Services Description Working
Group should investigate how MEPs are defined and used in the
description language, and assess the differences with the work which
has been done on SOAP. Then we can try to synchronize the work.
Jonathan has an action item to make sure that there is an issue in the
Web Services Description Working Group's issues list about this.

Useful information in this context is:
- how to define a MEP (the XML Protocol Working Group has made
  extensive work about this).
- a list of MEPs defined in W3C specs.

The Web Services Architecture Working Group should create a document
referencing this information. Thinking about this again, it is simple
enough that a short document maintained by the CG could do too.

Let us know if you are happy about this resolution.
