(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."
