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

Sanjay,
	I am sure that I can provide multiple use cases supporting the
position you propose, especially when we are expecting the ebXML payload
to be handed off to legacy backend systems.  
	I thought that we agreed some time ago that the case you outline
is supported.

Hi,

The question is 'Can an MSH send a sync ack and then an async response?'

Lines 1632-1643 (section 7.4.7) in ebMS v2.0 states:

	If the syncReplyMode parameter 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.

It would seem useful if the MSH could return the ack message
synchronously,
close the HTTP connection and
then send the business signal and/or response asynchronously.  This is
necessary if the business process is
long lived.  It also seems necessary for reliable messaging to work with
SyncReply set.

I would greatly appreciate an answer.

Thanks a lot in advance.
