WS-BusinessActivity Specification

["Dominik Heller" <Dominik.Heller@gmx.net>]

Hello,
I am reading through the WS-BusinessActivity Specifiaction right now and I am not sure if I understood the concept of the Business Activity scopes correctly. Well to picture the way of my understanding right now I describe a little scenario:
the top node of the Business Activity is a MixedOutcome Coordinator A which has three childs say, one AtomicOutcome Coordinator B with two childs and two separate MixedOutcome Coordinators C and D with two childs each.

So do I guess right that every coordinator is contained in a separate Web Service because of separate business logics and then is just plugged together  to a Business Activity?

The WS-BA spec is talking about nested scopes and that a business application is allowed to select which child tasks are allowed in the overall outcome. So in the end this means that the business logic of the Coordinator C chooses which of his childs has to close and which has to compensate and then notifices the Coordinator A that it is ready for closing or compensation, right?


Well thanks in advance for your help
