In our particular case, it would be the combination of the "adapter"
name and the CPA location (by partyid).  In other words, you'd configure
two named ebXML adapters (ie MSH) as ie "ebxml104" and "ebxml" (2.0),
both with the appropriate .jar, and then the respective CPA per
participant/party.  Otherwise, if you'd get the MSH version number from
the CPA, you'd have to write conditonal ebXML java code if you keyed the
adapter with just "ebxml".  Hmm .. I guess conditional code works fine
for minor version changes, ie 2.0-2.01, in which case the header would
contain the ebMS string.
