Re: Reasons for using XSLT to validate XML instances?

We use XSLT and XQuery (as well as XSD) to validate the XSLT and XQuery test
suites.

There may be other ways of doing it, but XSLT/XQuery are by far the easiest
way of validating a collection of documents, e.g. checking that every test
name is unique within a collection of several hundred test sets, or that every
benvironment nameb referenced from a test case actually exists somewhere
in the test suite, typically in a different XML document.

We also use XSLT and XQuery to control XSD validation of the document set: for
example an XSLT script can check metadata to see what schema a particular
instance document is supposed to be valid against, and invoke XSD validation
accordingly.

This works much better in 3.0 of course, because you really need try/catch.
