Dear Monica,

Hi All,

After yesterday's learning session, I've got a more concerte idea on BPSS
control flow and state management. However when it comes to Multiparty
collaboration, I still have some questions on it.

In the session, JJ said: "BC doesn't require coordination; MPC requires
separate agent for coordination (maintain state and context). You have a
party that may have a more central role, but there are still the multiple
parties. Need coordination interface (independent agent or driving
partner)." So how could we specify this "separate agent for coordination" of
MPC in the BPSS? For instance, in the attached mpc example (sorry for my bad
drawing), how could we specify the fork and join (choreography) for the MPC
in BPSS?

My second question goes into BusinessDocument. As I can see,
BusinessDocument is defined as the top level element in the BPS instance.
Does it mean that the evaluation of Document Content (Xpath for example)
could be done in anywhere in the BPSS?

Hope someone could help me. Thanks!

Best Regards,
Simon Lee
