David:
The latest working draft of the CPP/A spec has the following enumerated
values for syncReplyMode:
- none
- mshSignalsOnly
- signalsOnly
- signalsAndRespose
- responseOnly
The modes signalsOnly, signalsAndResponse, and responseOnly would also
include the MSH level Acknowledgment if Reliable Messaging is in use.
> "If the syncReplyMode is not none, a SyncReply element MUST be present and
> the MSH must return any response from the application or business process
in
> the payload of the synchronous reply message, as appropriate."
To avoid changing the above statement in the spec, we will have to interpret
the phrase "as appropriate" to mean that it applies to the modes
signalsOnly, signalsAndResponse, and responseOnly. In the case of
mshSignalsOnly, no application level payload is to be included. Furthermore,
clarifications can be put in the CPP/A spec.
On the other hand, if we are going to discuss and accept some or all of the
changes proposed by Chris and Doug, I don't see why we cannot also include
some clarification on sync reply mode.
