Re: [DS3] Request-response - revised

There may be more than one use case here depending on whether the
sender waits for a reponse or not.

The first case could be implemented using request-response in the
underlying protocol, even though the programming paradigm is message oriented.

1 XP Processor.

The second case could be implemented by the sender and receiver reversing
roles.
2 XP Processors.  In this case, the sender might require a facility for
matching
the response with with the sent message.
