RE: [wsbpel] Issue - 96 - Opaque Correlation Sets

I agree with Ugo except I would replace his example of reliability with session -- since it is the session that provides correlation not the reliability ;-)

I didn't read Peter's remark as requiring to "move outside of WSDL- and
Schema-described XML messages". I think his point includes cases where
the correlation protocol is a standard, WSDL- and XML-based WS
correlation protocol, but such that the BPEL language does not get to
directly manipulate it. The analogy would be the use of a standard WS
reliability protocol: even if it's there, the BPEL language itself does
not get to manipulate it.
