Sections 6.3 and 6.4 - Sections list services. Documentation looks pretty good. Do you intend/would it be a good idea to present state machines that show the various states for this and the lifecycles?

State engines delve into the processes behind the services. From SOA Reference: "Services are concerned with the public actions of each interoperating system. Private actions, e.g., those on either side of the interface, are considered inherently unknowable by other parties. A service can be used without needing to know all the details of its implementation. Services are generally paid for results, not effort."
