E903
      When a Producer has returned a Handle in response to a Consumer
invocation, the Consumer must ensure that Handle is supplied as a parameter
in any future invocations involving the Consumer and this Producer.

Excuse me if my questions are dumb--this is my first attempt to comment on
work that I still impresses me.  I apologize that other commitments kept me
from participating in the committees discussions around the time of the F2F.

Isn't this formulation a bit too word?

"When a Producer has returned a Handle in response to a Consumer
invocation...": When else does a Producer "return" a Handle?

>>> Not all "consumer invocations" _return_ a handle. Thus, only "when a
producer has returned a handle...".

"the Consumer...invocations involving the Consumer..."  Maybe I'm missing
something here, but does the Consumer ever not involve itself?

>>> I agree - this is a bit wordy.

Suggested revision: When a Producer has returned a Handle, the Consumer must
ensure that that Handle is supplied as a parameter in any future invocations
involving that Producer.

>>> I like that, except for the fact that some people (including me!)
thought that the use of "Handle" in a requirements document is not right, as
the concept of "Handle" is more of a interface specification type of entity.

So that I might better understand what is involved in this situation, Why
does the Producer need to have the Handle returned to it?  What will it do
with it?  (Just return it?)

>>> Actually, your suggested revision suggests to me that you understood the
requirement completey.

Also, the original requirement statement seemed to say something more than
stipulate a standard for Handle passing.  It was specifically concerned with
how the Producer indicates which ACTIONS, etc. must be directed to a
stateful connection (vs. what I would assume to be the initial current
stateless connection).  But I assume that might be clear from the signature
of a stateful service that it requires a Handle.  But couldn't the Consumer
call on the Producer for another stateless service? Thus, the phrase "any
future invocations" might be too broad. 

>>> Good point. How about "_some_ future invocations"?

Yes, that seems clearer Rich.

The Producer is always invoked by the Consumer (may be as part of
coordination/orchestration). I'm not sure what it means to embed a
parameter and I question whether we need to call out that the Handle may
only be part of a response. Reword to:

E903

invocation, the Consumer must ensure that Handle is supplied as a parameter
in any future invocations involving the Consumer and this Producer.

E903
                         The specification must specify the means by which
a Producer
indicates which actions, events and operations are to be redirected to the
stateful connection between the Consumer and Producer.

Reword to sync with E902:

E903
                         When a Producer has returned a Handle as part of
the
response to an End User invocation, the Consumer must ensure that Handle is
embedded as a parameter in any future invocations involving the End User
and
this Producer.
