RE: [ebxml-msg] Can an MSH send a sync ack and then an async response?

Arvola,  This would fix the problem.  Would there then be 4 new enumerated values?  None SignalsOnly ResponseOnly SignalsAndResponse mshSignalsOnly mshSignalsAndSignals mshSignalsAndResponse mshSignalsAndSignalsAndResponse  Cliff is right that this implicitly changes the behavior of the MSH (at least from a programmer's view) but can we avoid a change in the MS spec?
