Jean-Jacques,

>>I regard SOAP MEP as being at a higher level than this. IMO, they fit at the WSDL message level, not at the binding level.

Yes, at the message level. Although it is still an optional default extension, right? It is also tightly related to SOAP. Can someone use SOAP MEP without SOAP?

General purpose MEP, I believe, is part of the full-fledged orchestration already.

>>The current SOAP MEP is defined here [1] (request-response). Example 2 at [2] uses that MEP. Actually, most example today use that MEP, without knowing (just like Mr. Jourdain used prose).

Thanks for the info. It helped, although I still don't understand where would things like reqres:Role="RequestingSOAPNode" appear in the SOAP message.

PS. By the way http://www.w3.org/2000/xp/Group/1/10/11/OverlappingRRStd.png in [1] was forbidden for me...

I regard SOAP MEP as being at a higher level than this. IMO, they fit at the WSDL message level, not at the binding level.

The current SOAP MEP is defined here [1] (request-response). Example 2 at [2] uses that MEP. Actually, most example today use that MEP, without knowing (just like Mr. Jourdain used prose).
