XHTML as presentation "normal form"?

the application i'm working on generates content of several different
markup types (HTML, HDML, WML).  we'd like to move to XML morphed by
XSL stylesheets.  however, it's not as simple as just wrapping some
presentation around XML data--sometimes the presentation is data
also (button labels, headers, etc.).

we're considering using XHTML as a "normal form" of presentation, which
can then be pecked at by XSL stylesheets appropriate for a given target
markup type.  my thought is that this would save us from inventing our
own XML vocabulary for presentation, if XHTML's capabilities could be
considered a superset of those of HDML/WML.

with the above in mind...

1) are there freely available stylesheets that can transcode XHTML
to roughly equivalent HDML/WML?

2) if yes to 1), do these stylesheets handle HDML/WML's notion of
"decks" and "cards" well?

3) does my approach seem reasonable?

thx,
p
