After reading many of the threads y'all have sent, I am now thinking that a better axiom may be to state that a service is autonmous in its ability to control its level of opacity (do not think of a concrete service - just the abstract concept). > That a single service is an orchestration of several services is > not likely to be exposed but may be inferred by such things as > quality of service attributes. If you are referring to sectio 2.1.1, it is really more of when a service is a composite of two other services (or perhaps aggregation is a better term given the UML meaning). Duane
