For what it's worth here's are my ideas based on what other groups such as
ebXML and WS Choreography tend to use (I am off-line and so can't quote)
Really there are two levels:
1. Message Exchange Patterns are a short exchange of messages such as
one-way or request-response, together with associated
acknowledgement/receipt messages.
2. A Conversation consists of a combination of Message Exchange Patterns
where all the messages are related in some way.

The word "Conversation" is used because the exchange of information can
consist of an indeterminate number of exchanges of information as in a real
conversation between people. A classic example of a conversation is the
sequence of messages exchanged to place and/or change an order:

BUYER                     SELLER
       Order -------->
             <-------- Order Response
Change Order -------->
             <-------- Change Order Response
... repeat change order as required ...
Cancel Order --------> (only if required)
             <-------- Cancel Order Response

Thoughts?

David

So the collection of messages that manifest the exchange would be
