OWL-s and Parallel Composition

Hi,

Pardon me for my misunderstanding, but I am curious to learn whether
the OWL-S example [1] demonstrates parallel composition between
multiple entities ? To me, it seems that there exists a composite
service "FullCongoBuy", which in turn invokes a set of atomic and
composite services. All these composite services follow somewhat
sequential pattern (of execution). For example, the composite service
"CreateAcctSequence" performs atomic process "CreateAcct" followed by
atomic process "LoadUserProfile". Similarly, composite service
"SignInSequence" follows the same pattern.

So, at a higher level of abstraction, there seems to be a pure
sequential flow in which these services/functions are executed.

Please clarify me if I am wrong here.

Thanks,
- Jyoti
