XForms to XHTML using XSLT

Hello,

I just saw old threads about XForms to XHTML conversion using XSLT and I 
think this could still be a good idea for client-side XForms or for PHP 
only server-side XForms and there are today opensource solutions which 
are performing this conversion in Java.

What would the main problems rewriting a conversion tool with XSLT ? 
Effective full XSLT 1.0 support by browsers ? XForms specific CSS rules 
to translate ?

Thank you for your answers.
