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.

Subject: [ebxml-dev] Acceptance Acknowledgement Business Signal
Hello!
It's seems that ebMS 3.0 supports only Receipt Acknowledgement Business Signal.
How to send an Acceptance Acknowledgement Business Signal?
Thanks!
