How it will work with CSS? New parsing rules at least does not improve anything
and in reality take maths further from XML+CSS.

Put style sheet, script or whatever you keep in mind on the table.

If you introduce extra parsing rules then you break compatibility with

MathML support is binary, either it is supported natively or you see complete mess in browser.
Ian's proposal does not change its nature. What we propopse is gradual transition, with fallback mechanisms
that provide basic functinality in existing browsers.
