RE: [xml-dev] xquery and xsl

["Michael Kay" <mike@saxonica.com>]

Saxon already allows the second of these two:

http://www.saxonica.com/documentation/extensions/instructions/import-query.h
tml

The only real difficulty with the first (calling XSLT from XQuery) is
working out how things like import precedence should fit into the picture.

There's no difference in the data models and type systems used by XSLT and
XQuery, so there's no reason why they shouldn't interoperate at this kind of
level.
