RE: [xsl] XSLT and XML Schema

["Michael Kay" <mike@xxxxxxxxxxxx>]

Well, in principle an XML Schema document is XML so you can use it as an
input to your stylesheet. But it's not easy to process unless you know the
coding standards that have been followed, because there are many different
ways of writing equivalent schemas. The next Saxon release will offer an
"predigested" XML representation of the schema component model that aims to
help with that.

Incidentally, attributes should be regarded as unordered: the concept of
"the third attribute" is not very meaningful.
