Question on asynchronous business signals?

["James Wowchuk" <james.wowchuk@vcs.com.au>]

Title: Message

In reading through the BPSS1.10 spec I'm at a loss to understand how to distinguish in the BPSS where a business signal is to be returned synchronously or asynchronously.  Obviously the "timeToAcknowledgeXX" attribute in the <BusinessTransaction> will indicate if the signal is to be returned. But in the scenario where the "Acknowledgement" is returned immediately (synchronously) and the Business Signal "AcceptanceAcknowledgment" is returned later (asynchronously), does not the responsibility for the delivery mode fall within BPSS? 

 

In the case of an synchronous Acknowledgement, where no payload (Business Signal) is included, this has impact on the name of the Service element of the ebXML Message.

 

Possibly the complementary child elements of the CanSend->CanReceive or CanReceive->CanSend can be used to determine synchronicity?  Yet where the activities are asynchronous, how is it determined which corresponding CanReceive/CanSend element is used for the asynchronous Acknowledgement or Business Signal?  Or is that a question for the CPPA folks?

 

My apologies if this has been covered elsewhere but I find the archives difficult to search.
