Not entirely true. Remember that <optgroup>, in HTML 4.01, can't be
nested. Therefore, at best you only have two levels, which doesn't lend
itself well to a tree. Therefore, under the existing HTML standard,
there's little or no incentive to use a tree view. Heck, we have a hard
enough time getting vendors to implement |label| for <option> elements!
(Say, can we get <option label=""> support into the WF2 emulation for IE?)
