[xsl] XSLT 2.0 *and* XSLT 1.0 validation -- how to?

[Dimtre Novatchev <dnovatchev@xxxxxxxxx>]

Excuse me if this is a dumb or already discussed question.

Suppose I have XML Schema definitions for both XSLT 1.0 and XSLT 2.0. 

How will a validating processor know which schema to apply for which
language? Both languages are defined in the same namespace... Was this
an intentional effort of the XSLT 2.0 WG and why?

Thanks,

Dimitre Novatchev.
