Re: [ws-rx] i089 proposal

1) Yes - I completely aimed this to be a specific model for RM. I would 
be happy to include language that indicates that if a more general 
purpose firewall crossing mechanism was in place this should not be used.
2) The wsrm:Identifier is a required part of my proposal, and therefore 
this proposal is completely tied to the use of RM.
3) The suggestion of using messageNumber is interesting. The motivation 
for using a message ID was that there may be situations where I really 
want the response to a given message. We do not - so far - have any 
concept of a response to a given RM messageID, so that seemed like a new 
concept to me, whereas WS-A systems do keep track of responses to given 
messageIDs. But I'm not averse to your suggestion. However I wish to 
make clear that in my proposal you MUST have both the Identifier and the 
messageID - so it is still very closely tied to the offered sequence.
