WS-Acknowledgement and WS-Callback provide a framework for an 
acknowledgement-based reliability protocol that is an alternative to 
WS-ReliableMessaging (there is overlap in the authorship of these - 
there is less connection IMO to WS-Reliability). It is possible there 
will be some convergence of these specs.

One of the architectural concerns I have had about WS-Acknowledgement 
and WS-Callback is that they are basically using SOAP headers to extend 
the WSDL 1.1 MEPs. This is mixing up two architectural layers that 
really should be kept separate, IMO. WSDL 1.2 will provide a better way 
to do this. IMO it would be better if this extension could be done in a 
way that provides a better migration path to WSDL 1.2.
