Omri Gazitt: One interesting existing application of this pattern is Atom (a publishing/blogging protocol built on top of SOAP). Looking at the Atom WSDL, it looks very much like WS-Transfer - a GET, PUT, DELETE, and POST (which is the CREATE verb specific to this application). So Atom could easily be built on top of WS-Transfer.

Randy: Interesting thought. I'll have to dive into WS-Transfer.
