Service Type == Set of Possible Application States

As I have said earlier, in my opinion service types are defined by the set of hypermedia semantics (media types, link relations, ..) they use. Because representations sent by services of a given type are composed of hypermedia semantics from the service type's set it can be said that the service type defines the set of possible representations.

Given that a representation returned by a server corresponds to an application state it follows that a service type defines the set of possible application states.

I like that.
