Perhaps I didn't look at your code very closely, but after you've
made the xml string ($xml) what happens? Shouldn't your action output
(return) that xml?
I'm not sure if 1.1 has the ability to use RequestHandler to respond
as xml, otherwise you could just make an empty layout, which would
only display your xml data (or more specifically return your xml data
back to jquery).
p.s. do you really need 'onchange' in your select tag? I'm pretty sure
with jquery you can "listen" for an event on a given element.
