Nice idea, perhaps, but seems a little on the "heavy" side.  Asterisk 
programmers tend to be much more pragmatic.  Simple variable passing 
seems to be adequate for any applications that I could come up with. 
Perhaps XML could be passed in a completely different message type, 
but my ideas for variable transmission are part of a call setup.
