The idea of multiple levels of xforms compliance seems to suit the needs of
the wide variety of clients and developers that are likely to benefit from
this standard.  In fact, it nicely answers many of the issues raised in the
working draft regarding whether to support or not support certain features
that would be "too expensive" for small devices.

A more difficult question will be what constitutes the details of each
level?  So far, I like the outline you propose.

Would the following solve your problem:

We define a new level of XForms conformance next
to the two existing ones:

XForms Core: The basic XForms concept of 
  Model-View-Controller, the binding mechanism
  and the core XForms module(s) (<xform>, <model> &
  <instance>). You may yourself choose and use any 
  pre-existing or custom model language and any
  UI language as well as of course any arbitrary
  XML instance for data.

XForms Basic: XForms Core + Concrete Model as 
  W3C XML Schema Subset (Part 2 Datatypes) 
  + XForms UI.

XForms Full: XForms Core + Concrete Model as 
  Full W3C XML Schema + XForms UI.

Food for thought. Others on this list: Opinions?
