How can I reference the value of another attribute in a maxExclusive
restriction?
Can I do it with a W3C schema, or I need a Schematron schema as Jeni Says?

And another question, I haven't heard anithing of Schematron, It's a comercial
tool?
It's an extension to W3C Schemas?, or is a completly different schema language?
