Schematron tutorial

Schematron is a validation language that goes beyond the capabilities of DTD, W3C Schema and RelaxNG. Using XPath expressions, it can validate almost anything in an XML document. No prior knowledge of Schematron is required for this tutorial. We start at the very beginning. But because the language is simple and elegant, we'll soon reach some more advanced topics (like abstract rules and using XSLT). The tutorial will be a mix of theory and hands-on exercises.
