I was only trying to point out a potential issue in 1.0 so that
it can be avoided in 2.0. ITS 2.0 should use either XPath 1.0 or
2.0, or it should have a way to specify which version is in use.

I'm not sure we're talking about the same thing. Whether there is
a schema is up to the content creator. I didn't mean to imply that
XPath 2.0 requires people to create schemas or associate them with
their documents.

But if a document does have a schema associated, it must be read.
Or am I wrong? Can I write a conformant XPath 2.0 implementation
without the ability to read XSD files?
