Re: Exchange type issue

While we agreed in issue X that a choreography should only "officially" support the use of in-only, in-out and robust in-only MEPs from WSDL 2.0, there's nothing as far as I can see in the spec that indicates that a choreography could not describe any of the WSDL 2.0 MEPs. This implies that we could support responses that wouldn't be matched to a request. If we have but one response in the choreo, and that is not matched to the initiating request, we in effect described an out-only with that choreo.

mm1: This relates to previous discussions we had a conscious decisions 
about the explicit MEP supported. One comment related to this to 
consider is that WS-BPEL specifically prohibits the use of this pattern 
and any definition that includes it is rejected in static analysis. This 
may create an incompatibility in endpoint generation if WS-BPEL is the 
target. Thanks.
