mm1: In appendix A of the BPSS 1.1, please look at the XML schema. If I 
understand your question correctly, and I am not, we need to resolve:

   1. What starts the binary collaboration? The binary collaboration
      (Business Transaction Activity or Collaboration Activity has a
      start state that signals the first activity in the binary
      collaboration). The Start element is described as: The starting
      state for an Binary Collaboration. A Binary Collaboration should
      have only one starting activity.
   2. What is the first binary collaboration when a compound binary
      collaboration applies, other than the order they are represented
      in the XML schema? If this properly represents your concern or
      question, we can  then start to discuss with ebBP team.

Thanks.
