If they were paying, either for the specs or for the products, then they
might have more ability to influence the outcome...

Yes, this is likely. We're exploring this area at the moment: for
example there are suggestions that a stylesheet should be able to say
whether it requires to use a schema-aware (or non-schema-aware)
processor, to ensure interoperable results.

Note that we already have this in a very basic form with ID attributes
in XSLT 1.0; these will be recognized by the id() function or not,
depending on the XML parser you use.
