I don't want to answer for Jeremy, but I'm assuming he meant well-formed
XML documents (*not* tag soup) which differ from 'valid' XHTML (per DTD)
primarily via the use of namespace declarations (the most common case). 

I think it would be a *serious* mistake for GRDDL to exclude this family
of documents (even implicitly) or to allow an interpretation that
suggests such an exclusion.  This is mostly a matter of clarification
IMHO as (by virtue of the normative sections being declared in XPath)
this is clearly not the case (however, the use of the 'valid' XHTML
qualifier seems counter-intuitive).  

I.e., a GRDDL-aware agent which comes across XHTML which is invalid WRT
to one of the 'sanctioned' DTDs will still compute GRDDL results.  So,
'validity' would seem to be of no consequence.

John's suggestion [1] about an interpretation of validity that permits
this is very relevant to this point.
