RE: simultaneous execution

I think we are actually agreed on two objectives:
1. The need to create choreography definitions that are indpendent of the
message format, and
2. To define how choreography definitions are bound to Web Services and WSDL
in particular.
 
I don't think these objectives are mutually exclusive and we should be able
to do both. Does anyone disagree?

[FAC] I believe we can do that without sacrificing broader applicability of
the choreography.  I'm more concerned that we not link the choreography to
the message formats. 

If your concern is about about linking the choreography to the message
formats on the wire, I would like to point out, as I have done before, that
a portType/interface message structure does not imply any commitment to a
format on the wire. It's only when the portType/interface is bound to a
particular service that the wire format is defined.
