RE: Collaboration Services (was: Business Service Interface)

Thank you for this excellent example, however, I think that it is important
to separate the message exchange from the internal business logic that one
particular role may want to implement on its side of the collaboration to
best serve its own interest.

In Dale's example, as well as many others, it is not just a question of
one particular partner's internal business logic.  Both partners need
to agree on some rules of engagement:  in Dale's example, at least
the time-limited reservation of parts.  Otherwise the whole business
collaboration does not work.  In other words, there is a public logic to
the whole collaboration that must be shared to some extent.
(That is not to deny the aspects of private interest.)
