Yes, IMHO. For example, I'd like to see a more business-oriented explanation of "The requestor is able to correlate a response received in a separate message (and protocol invocation) with the original requesting message."

Remember that we're not trying to design an actual choreography language, just figure out the scope of a WS Choreography WG. I do think that the suggestions, such as the "state machine in XML", help us think about these requirements, but let's not get carried away :-)
