WS-Addressing 1.0 stateful services

WS-Addressing 1.0 uses the WS-Addressing EndpointReference type as a state variable to maintain a stateful service.

The EndpointReference type is independent from the transport layers. (See WS-Addressing 1.0 EndpointReferenceType). The session state is conveyed from the client to the server as WS-Addressing 1.0 reference parameters.
