Re: [ebxml-cppa-negot] Which binary collaboration to start with?

Hi Monica

Will read the BPSS 1.1 Specification this coming weekend, otherwise I
just cannot keep up the discussion.

SS1: First I notice the new Package element. A list of
BusinessTransaction elements, a list of BinaryCollaboration elements and
one MultiPartyCollaboration.

SS1: The BinaryCollaboration does have a Start element which shows which
shows which BusinessTransactionActivity opens the collaboration.

So I think this point is OK.

SS1: Yes this is the question I have. The MultiPartyCollaboration from
Appendix A of the BPSS 1.1 does not indicate which BinaryCollaboration
is the opening BinaryCollaboration, or it is not obvious to me. 

If the order of the invocation of the BinaryCollaboration is of
importance (what I think is) it seems to be neccessary that the Schema
defines that; Like the Start element in the BinaryCollaboration does.

Kind regards
