Just clarifying a rather small part of the big puzzle!

It is enough, for a client to interact with a service that implements a WSRF specification. Note: I did not use the term build on top (this term might imply that WSRF implementations have to be provided by the infrastructure). 
The service simply implements one of the WS-* specifications (ie WSRF)! The client then uses messages exchanges as defined in that services description.

Absolutely, this is true of any web service specification, including WS-Transfer (no offence intended to any WS-* specification!)
