neat!  i'd thought about trying this but figured that xml vs html issues
would make it too hard - but it sounds like you already got pretty far.  if
it's making it as far as the double id="..." attribute then i think the
chances are good that it can work, at least in firefox.

there is a mjt.js bug here... as you point out, the browser tolerates the
duplicated id="top" in html, but xml is not so forgiving.

i'll be pushing out a new version of mjt.js this week with a fix for this
bug as well as some other goodies.  i need to test the new goodies on
ie6 first :-/.
