I agree with Richard. Like SGML, groves can be very complicated or
simple, as required, and XML can easily use a simple model -- just
enforce a single list of supported modules, as XML enforces a single
SGML feature list and declaration.

Why redo all of the work for XML that's already been done in the
HyTime annex and DSSSL standard? I can see no advantage in
re-inventing the wheel for XML: it will simply force software and
documentation to support two different, incompatible approaches.

I do agree that we need more and better documentation on groves, but
we will need to document a proprietary XML approach as well.

For more on the grove support currently available in SP (for full SGML
and XML), see

All the best,

David
