Here is an example using IE6, SvgViewer 3.0 and Mathplayer 1.0 beta 4.
Please note, that i don't use the universal MathML stylesheet (UMSS) here,
since nothing comparable exists for Svg. So the resulting document
XHTML/Presentation MathML/SVG is unfortunately not cross-browser enabled.

  <p>In SVG a homogenous transformation matrix looks like this.<p>
