From the write up, I'm not quite sure.  Please answer this question.
Suppose we replaced transaction IDs in the CPIM document by three
other IDs.  For instant messages, we use message IDs, for
subscriptions we use subscription IDs, and for notifications, we use
notification IDs.  Have we changed the intent of CPIM?  Is there an
essential reason why the IDs for the three different CPIM operations
have the same name, or is the reason simply a matter of economy of
keystrokes?  It appears that transaction IDs are used for different
purposes by the three operations.  For example, sometimes they are
used to match responses with requests, but in the case of
notifications, this use makes no sense.
