I wholeheartedly DISAGREE. XForms in my mind is a way to declaritively specify
forms that the rendering authority can render as they see fit. In my mind what
you are talkign about is XSLT and not XForms. I certainly would want to keep the
minimum of "appearance" information out of the form. What if someone contacts
your form via a Cellular Phone. Then just exactly how are you going to pop open
microsoft word on a 4 cm x 4cm screen.

If you want to customize appearance you are seriously barking up the wrong tree
in my opinion and should be looking at XSLT.
