request for clarification of SOAP/HTTP binding in SOAP 1.2

Hi Folks,

The WSDL WG is interested in the possibility of supporting a WSDL 
binding for SOAP/HTTP that supports asynchronous responses (for WSDL
in-out MEPs). This note is NOT a formal request from the WS-Desc WG
but rather a personal one from me as a member of that group.

I'd like to understand the precise semantics of how a SOAP request-
response MEP is bound to HTTP in the SOAP/HTTP binding of SOAP 
1.2 [1]. Is it the case that [1] states that that the request
message be sent on the HTTP request message and that the response
must come on the HTTP response? Alternatively, does that binding
permit me to send the SOAP request message on one HTTP request-response
(maybe with the response saying 201 OK for example) and then for
the originating SOAP node to receive the response by the other node
doing a 2nd HTTP POST to it? (For which the the originator may HTTP
respond with 201 OK, for example.)

Thanks for your views on this!

Sanjiva.
