Well, the latest WSDL Message Patterns draft mentions a transport-level correlation mechanism (that's what "the same channel" seems to mean). Are you saying that the WSD group has decided not to touch that area at all (which could explain dropping the Request-Response MEP in favor of just In-Out)?

That might be a proper decision for the WSD group, particularly in light of the time pressure it is under. On the other hand, if that group does not address it, other groups will, as you say (in addition to the ones you mention, BPEL has also its own way of dealing with it). The problem is, as usual, that those groups might introduce different concepts and mechanisms that, in the end, will not easily interoperate.

Ugo
