Re: [sca-assembly] [ISSUE 33] Updated Proposal for Issue 33

Mike,

My initial reaction to this is that
it conflicts with the existing conversational support, although I see that
there is a new issue to remove that support from the spec.  If that
doesn't get accepted, are you comfortable with the spec including all of
callbacks, conversations and async invocations?

The text says: "the binding must
be able to treat the transmission of the request message separately from
the transmission of the response message, with an arbitrarily large time
interval between the two transmissions.".  Does that leave space
for an implementation to include timeouts, or to hold correlation information
non-persistently?  Even for HTTP some amount of asynchonous invocation
is possible, at least from the point of view of the interacting components,
although the connection would be lost if either party terminates or some
comms error occurs.

I'd note that for the web services example
given, the non-anonymous response URI allows a client of a service to act
asynchronously, but it does not mean that the service itself will dispatch
the request on its target component and handle the response asynchronously.

Regards, Simon

Subject	[sca-assembly] [ISSUE 33] Updated Proposal for Issue 33

Folks, 

Here is an updated version of the proposal for Issue 33 following the discussion
on the call yesterday: 




This is the version that I am sending to the other TCs.

Note that the current Assembly specification does not define the requirements
that bidirectional interfaces place on bindings, so the text in this proposal
is the first place that this is defined for the Assembly specification.


Yours,  Mike.
