That is just what the XML Infoset WD is all about.  There is no problem
with expressing the XML Infoset as a grove, and the only reason it
isn't going to be in the WD is that I don't know how.  I do know how
to do RDF schemas, so there will be one of those instead.

AFAIK the Infoset meets the grove object model: there are objecdts with
properties, some string-, integer-, or boolean-valued; other properties
are either ordered or unordered lists of other objects.
Does the grove model capture the difference between ordered and
unordered lists directly, or does that require extra properties?
