Title: RE: [ebxml-msg] SynchReply module

Bob,

I believe that there are cases where is *is* necessary. The SHOULD refers

to the receiver's ability to keep open a connection indefinitely (which is

unlikely). In the event that the connection is broken, then the sender will

likely not ever receive a response.

This wording may need some further work;-)

So is it really necessary or not?  I like "SHOULD", and
think the word 'necessary' is a bit too strong.  I'd vote for 'desirable'
as a replacement word.

All,

  
Here is the proposal for the SyncReply module.

  
Cheers,

X SyncReply Module

  
There are use cases where it is necessary for the sender
of a message, using

  a synchronous communications protocol, such as HTTP, to
receive the

  associated response message over the same connection that
the request

  message was delivered. In the case of HTTP, the sender of
the HTTP request

  message containing an ebXML message needs to have the response
ebXML

  message delivered to it on the corresponding HTTP response
message.

  
In the case where there are intermediary nodes (either
ebXML MSH nodes or

  possibly other SOAP nodes) involved in the message path,
it is necessary 

  to provide

  some means by which the sender of a message can indicate
that it is 

  expecting a response

  so that the intermediary nodes can keep the connection open.

  
The SyncReply ebXML SOAP extension element is provided
for this purpose.

  
X.1 SyncReply element

  
The SyncReply element MAY be present as a direct child
descendant of the 

  SOAP Header

  element. It has the following attributes:

      - SOAP actor attribute with a value of 

  "
http://schemas.xmlsoap.org/soap/actor/next
"

      - SOAP mustUnderstand attribute with a value of '1'
or 'true'

  
If present, this element indicates to the receiving SOAP
or ebXML MSH 

  node that the

  connection over which the message was received SHOULD be
kept open in 

  expectation

  that a response message will  be returned via that same
connection.
