# Template for XHTML + MathML + SVG    + JavaScript + div + CSS

Reference for the DTD (Document Type Definition) used in this file:
http://www.w3.org/TR/XHTMLplusMathMLplusSVG/#howto-xhtml

This is the page where I got the code to enable writing to the div:

This file has been validated:
XHTML: http://validator.w3.org/
CSS: http://jigsaw.w3.org/css-validator

The extension ".xml" displays the page fine, but it doesn't validate.
