Issue-6692 - Interim agreement draft

The following is a draft that incorporates the current state of  
agreement on Issue-6692.
Note that within the document there are several areas marked "TBD"  
which represent further aspects that are yet to be thrashed out.
This version has been reviewed by both Microsoft and IBM and both are  
agreeable as to it use as the reference for further issue negotiation.
The summary of further work needed is :
1) Fault behavior relating to delivery extensions as the original  
fault definition related to @mode
2) extension negotiation behavior if any since the original @mode  
fault optional detail element was thought to provide some negotiation  
mechanism albeit unreliable
3) Use of the word "Push" rather than simply the one default method of  
notification delivery.  Nothing particularly distinguishes "Push" from  
normal asynchronous delivery and its use in th text is infrequent

I would be interested in discussing this on the next call as well as  
the opinion of folks as to the potential division of this issue into  
three additional issues as represented by the points above.
thanks
