Well, Transfer is the application is this case - so yes the application is
defining the meaning of how to treat the XML in the Body.  Vanilla 
defines Put as "blind replace", while fragment Transfer modified it to be
"interpret the XML as an instruction".

This might be true if RT were a separate application but its not.  RT is 
extension to T.  This fragment stuff is being done (no matter how its 
packaged in the specs) as part of the T application.
