Nick is correct, the MS was designed to support RPC like behavior where a party
sends an ebXML Message containing a "REQUEST" which results in an immediate
synchronous or asynchronous "RESPONSE". A scenario related to regrep would
appear as follows:

ebXML message REQUEST: I want your trading partner profile
ebXML message RESPONSE: OK; here it is

In the above scenario the ebXML header document in the REQUEST message
identifies the service (a.k.a. procedure) being invoked, in this case it would
be a regrep service (e.g.  TPINFO) and the payload contains the "call
parameters" (e.g. DUNS Number of trading partner profile being requested). The
RESPONSE contains an ebXML message indicating a SUCCESS status in the ebXML
header document, the payload  contains the requested information (trading
partner profile) in XML (tpaML).
