Was (RE: T2 SyncReply and ReliableMessagingMethod in QualityOfServiceInfo)

Thanks, David, that was long!

The answer to my questions is probably somewhere in there but I may have

Question 1:  How do we do end-to-end RM irrespective of IM RM, i.e. how do
request an end-to-end Ack?  Is it the DeliveryReceipt or is there something
[David B] You use the Delivery Receipt.

Question 2: In a multi-hop situation (more than one IM) how do we avoid
the IM change AckRequested and thus have the wrong value for all subsequent
[David B] The IM can change the AckRequested since on hops where another
Reliable Messaging protocol (e.g. MQ Series) is being used the Ack is not
needed. The IM just needs to determine that:
a) The message is being sent reliably (DeliverySemantics="OnceAndOnlyOnce")
b) The values to use for ackRequested, syncReply etc to use for the next hop
depending on the transport that is being used.
