last few sentences.

Service / Action

Hima will be updating the issues list in his document.  Dale asked what the
service and action values in a SOAP header would be when a message combines
an MSH signal and a business action.  Arvola replied that according to the
MSG spec, the service and action for the business action would be used.
Dale then inquired about the case of both a business signal and business
response; in that case Arvola indicated the answer is unclear.  Arvola
noted that BPSS doesn't have the notion of synch reply; Dale thought that
was reasonably an implementation decision for the CPA.  Arvola thought that
synch reply was implicitly overriding some of the timing parameters.  Tony
responded that timing and synch reply can be considered independently ?
regardless of synch reply, all, some, or none of the signals and actions
will meet the timing constraints (the fact that some signals and actions
may arrive together doesn't change the assessment of whether or not they
meet their timing constraints).  Parties who agree to use synch reply mode
should take that into account when specifying timing parameters.  Agreement
authoring tools might provide advice accordingly.
