    Yeah, I'm aware of that. The idea with <select multiple> was to 
allow something that could, if the UA vendor chooses, be rendered as a 
simple tree view. Full-blown tree view markup would probably exceed menu 
systems in complexity. (That's a thought: reuse some of the menu markup 
for tree views...)
