Background
From The MODAF Service Oriented Viewpoint
p13:
It is generally considered good practice to make services stateless – i.e. consumers of a service are not aware of what state the service is in. However, in specifying a service, it is often necessary to specify the allowable states so as to constrain how implementations of the service will behave. SOV-4b is a specification of those states, and the possible transitions between them.

An SOV-4b may also specify performance constraints (ie the maximum duration a service may be in a particular state.
