RE: [ws-caf] Questions about section 3

["Murray, Bryan P." <bryan.murray@hp.com>]

Section 5.2 is the other section containing message descriptions and it
is fairly careful to indicate which follow-up messages can occur for any
message received by the ContextService and which messages must contain a
context header.

There are aspects of what I mentioned for section 3 that can also be
applied to section 5.2:

- what should the user context service's behavior be if it receives a
completed message without having sent a complete message?

- is there a time the user context service should be expected to wait
for a follow-up message? This is closely related to what is the expected
behavior if a follow-up message is never received?

is the latter part of this question generically applicable to all 
asynchronous callbacks in WS-Context?
