I said *NOTHING* about sessions.  However I did bring up correlation
because that is *EXACTLY* what WS-A is using the element currently
named "MessageID" for.    It is not using MessageID for identifying all
messages (it only identifies messages that require a response) nor for
replay attacks (it's missing some additional parameters that would
make this reasonably doable), nor for reliable messaging processing
(again, missing some additional parameters).

IMHO, Much of the confusion/discussion on this list over the past
few months on this subject have all been because people are
misinterpreting the purpose of this element because of the name
of the element.
