RE: [ws-rx-implement] [Fwd: FW: about InteropScenarios 0.8,scenario 1.4]

[Marc Goodner <mgoodner@microsoft.com>]

I'm not sure I agree with this text. How about the following, I think it captures the intent of the proposal below.

Replace:
"The CreateSequenceResponse is the first message to be sent on the "back channel."

With:
"The CreateSequenceResponse may be sent on the HTTP back channel or, when possible, via a new HTTP connection to the ReplyTo URI. Clients must be prepared for either case."

(not sure I can post on this list yet... only "observer" so far - Paul can you forward to list in case? Thx.)

Comment on Interop Scenarios 0.8:

Scenario 1.4 should not state:

"... The CreateSequenceResponse is the first message to be sent on the "back channel." "

Indeed, the XML for CreateSequence messages does not use ReplyTo:anonymous (consistently with all other exchanges in this scenario)

So this means the CSR SHOULD (not a MUST, though) be sent back on a new HTTP connection , per WSA SOAP binding spec (".. When "--/anonymous" is not specified for the response endpoint, then ... Any response message SHOULD be sent using a separate connection and using the address value specified by response endpoint.")

Propose to replace:

" The CreateSequenceResponse is the first message to be sent on the "back channel."

With:

" The CreateSequenceResponse, like other response messages to RM protocol messages for sequence management, is sent over a new HTTP connection to the ReplyTo URI."

Now, assuming some destination implementation may decide to not follow what is so far only a WSA recommendation, the client side should not choke on it. So one could add:

"in case an RMD sends back these responses over the back-channel, the client must accept these."
