• Use the "-//W3C//DTD XHTML 1.1 plus MathML 2.0//EN" DTD. This makes it easier for your XML editor. It is also useful to define the mathml namespace as na entity (Make typing shorter for each "math" fragment). See file xhtml-plus-mathml-test.xml. Important: le fichier doit etre servi come *.xml !! (ou à TECFA comme *.xhtml, ce qui revient au même)
• Use MathML by just declaring the namespace: See file xhtml-with-mathml-test.xhtml.
• Tested with Mozilla 1.2
