Does this really answer the original question you posed? Is the sample 
process fragment you supplied considered illegal?

I can easily imagine someone trying to exploit such a "feature" if it 
was not explicitly banned. Borrowing from your example:

      <receive partnerLink="A" createInstance="yes".../>
      <receive partnerLink="B" createInstance="no".../>

This could be used by partner B as a kind of polling mechanism to see if 
partner A has done his thing yet. Kind of an event handler for process 
instances that don't exist. Useful for non-deterministic (parallel) 
sections of a choreography.

Do we wish to support this usage, or ban it? I think we need some 
explicit wording one way or the other.
