RE: [soa-rm] Re: SPAM-LOW: Re: [soa-rm] Requesters vs. Consumers

Ron:

Not yet. There are two issues before us.

1. The term for the concept: I think it is safe to say that "service
consumer" is the term we should use for , well... service consumers.

2. Is the concept in the reference model: Whether or not that is part of
the reference model is another issue.
