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).

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).
