Some issues to consider in the MOM

1. Does correlation still belong?
2. Should we have message intermediaries?
   Pro: Allows us to explain router-style intermediaries
   Con: If a message has been modified in *any* way, is it still the 
same message
3. The SOAP notion of an envelope is essentially the outer wrapper of 
the message infoset. However, SOAP 1.2 seems essentially silent on the 
transport aspects of messages. I don't think we should be so silent; 
especially since we cannot explain routers without it. However, the 
natural place for this is in the envelope (after all, envelopes have 
addresses written on them!)
3a. In effect, is an address that is used by a transport mechanism part 
of the message or not? What about message oriented audit trails? (Where 
the message carries with it a record of its trajectory through the 
system.)
3b. The current definition of envelope is not really consistent with 
the SOAP view. However, it *does* capture the concept of a message's 
address.
4. The diagram that is in the text does not reflect the discussion that 
we had in Palo Alto. That includes delivery policies as well as 
intermediaries.

Probably there is more, but this is a pretty good list already!
