Re: [wsrm] Need to rethink semantics of duplicate elimination behaviour
Jacques,

I am not sure what you mean.  A message may be resent after the 
receiving application has processed it.  The previous acknowledgment 
could easily have been lost.  In effect, the sender is performing the 
resend in order to retrieve the missing acknowledgment.  Of course, that 
sender does not know or care whether the original message or the 
acknowledgment was lost.

This all means we need acknowledgments for all messages sent reliably 
whether duplicates or not.

thanx,
	doug
