No, one MessageUnit is just a subcase with MessageUnit.length==1

This handshake is not enforced by xmlBlaster, the two participating
clients need to aggree on a client specific protocol.
If this feature is of general interest and generic describeable it could
be implemented as a new xmlBlaster feature.

This case should be covered by xmlBlaster, but i just have noticed
that a testcase is missing, i try to provide one ...

That should simplify the use case.
