If the proxy has support for getting the XML it shouldn't matter ?

Yeah, I think we need to be able to guarentee that whenever there is
a '<graphics type=vnc>' tag, it will always have a port number attribute.
If the port number is missing some of the time, people won't be inlined
to make use of it & will go back to hardcoding stuff in the application
code instead.
