Re: [xsl] xml validation

[Wendell Piez <wapiez@xxxxxxxxxxxxxxxx>]

Max,

I have used an XSLT 2.0 query language binding in Schematron to 
achieve things very similar to what you are describing, including 
validation of XSD datatypes. Yes, "castable as" will work.

Also, some Schematron implementations (including the reference 
skeleton implementation in XSLT) allow you to mix XSLT into your 
Schematron, which is a killer combination, since you can then write 
XSLT 2.0 functions to use in your Schematron as well as templates for 
enhanced reporting.

Cheers,
Wendell
