Neither do I, and, to be honest, that wasn't what I was trying to achieve. 
Obviously if you have some clients which can validate client-side and some 
clients which can't you are going to have to duplicate the validation 
server-side -- but in a network of heterogenous agents you have to do this in 
any case, because you cannot depend on the agent at the other end behaving in 
the way you expect it to.

All I was trying to achieve was to have one form generator which generated 
the structure of the form for all clients, and then use XSL-T to transform 
this for (e.g.) HTML and WML clients which don't support the full XForm 
functionality. My current belief, having spent a couple of days poring over 
the problem, is that this can't be done efficiently with XForm, and I'd be 
better off writing my own custom forms DTD which can be translated 
efficiently to XForm, to HTML to WML, and to other as-yet-unknown formats.
