Anecdotally speaking, using the AAException signal is more common than always sending the Acceptance Ack (or both). Conversations tends to get a little chatty
using both. And if there is a need to go beyond state-alignment style signaling of exceptions, it might be worthwhile to look into some of the “transaction” based specifications.

Where we tend to use acceptance acknowledgement signals is in the negative sense.
If we cannot get a business service to process an inbound request and produce a sensible
business level response (positive or negative) we will instead send an acceptance exception as an indication that there was a business level problem with the request of an unanticipated nature.
The idea being that in a request response pattern the client business service will then always
get some form of response even if it is an exception.

Acceptance Acknowledgement as a business level signal is described in an auxiliary documentation section
http://docs.oasis-open.org/ebxml-bp/2.0.4/OS/signalSchema/documentation/
RosettaNet had dropped AcceptanceAcknowledgements in RNIF 2.0 due to lack of customer demand, and ebXML included both Receipt and Acceptance Acknowledgements
and their Exceptions.
It is IMO left somewhat as “some assembly required” by a community that seeks to adopt it.
There is the following description.
The schema describes a potential Acceptance Acknowledgement. And then the details needed for a community usage can be profiled from these snippets.

Hello!
It's seems that ebMS 3.0 supports only Receipt Acknowledgement Business Signal.
How to send an Acceptance Acknowledgement Business Signal?
Thanks!
