Instead of "does not depend ..." I would say "whose invocation does not depend ...". The AGENT itself might very well depend internally on the context related to the invocation of other SERVICES (typical example: a BPEL process, which is offered externally as a Web service but depends internally on the invocation and coordination of a bunch of other Web services).
