Re: [Filter Effects][css3-transforms] Using MathML for formulas

Without even having noticed this thread (Dirk just pointed me to it), I 
added MathML supported by MathJax to the SVG 2 spec earlier today.  It 
is currently referencing the CDN copy of the library (although the 
stable version, not the "latest" link).  It works pretty well -- I've 
currently got it using the SVG rendering mode, since it looks nicer in 
than the HTML+CSS, IMO at least.

I replaced one <pre>-formatted equation here:

Anyway, I'd love to keep using it in the spec.  I'd be fine with adding 
a local copy of the library to the svg2 repo if necessary.
