Ok. I don't see a problem here other than the W3C perhaps
needing or wanting to do as was done with schemas
and create a single official specification for the
rule system. Schemas are ready for prime time.

Yes. That is my point (in answer to Len's question),
* that grammars and path-based rule systems are not equally expressive;
* that grammars and path-based rule systems are not a subset, either of
the other; and
* that the structures that grammars can handle which path-based rule
systems cannot are less useful and of dubious merit (because there
are structures present which are not labelled and therefore
to standard API-based systems that
just use the infoset; to say these structures are significant puts us
on the slippery slope to PSVI.)
