How to validate an XHTML 2.0 document

To validate an XHTML 2.0 document, you must include the following Relax NG Schema in the XHTML 2.0 document: http://www.w3.org/MarkUp/RELAXNG/xhtml2.rng. Once you've included this schema in your XHTML 2.0 document, XMLBlueprint XML Editor will support XML Completion for your XHTML 2.0 document. To validate your XHTML 2.0 document, open it in XMLBlueprint XML Editor and click XML > Validate.

To use this Relax NG Schema, start your XHTML 2.0 document with:

<?xml version="1.0" encoding="utf-8"?>

<?blueprint

      namespace="http://www.w3.org/2002/06/xhtml2/"

      schema="http://www.w3.org/MarkUp/RELAXNG/xhtml2.rng"?>

<html xmlns="http://www.w3.org/2002/06/xhtml2/">

</html>
