Proposed updates to Doug's text

Here are my suggested edits, incorporating Paul Cotton's second point.

Since the message exchange pattern use by MakeConnection is an unusual 
pattern, the following points
need to be reiterated for clarification:
● The MakeConnection message is logically part of a one-way operation; 
there is no reply message to the MakeConnection itself, and any response 
flowing on the HTTP backchannel is a pending message.
●Since there is no reply message to MakeConnection, the WS-Addressing 
specific rules in Section 3.4 “Formulating a Reply Message” are not 
used. Therefore the value of any wsa:ReplyTo element in the 
MakeConnection message has no effective impact since the WS-Addressing 
[reply endpoint] property that is set by the presence of wsa:RepyTo is 
not used.
● In the absence of any pending message, there will be no message 
transmitted on the transport
back-channel. E.g. In the HTTP case, just an HTTP 202 Accepted will be 
returned without any SOAP envelope in the HTTP response message.
● When there is a message pending, it is sent on the transport 
back-channel, using the connection that has been initiated by the 
MakeConnection request.
* The MakeConnection message and operation is deliberately excluded from 
the WSDL in Appendix B, as this behaviour can only be partially captured 
using WSDL.
