[uf-new] an equation/MathML/TeX microformat?

[Paul Topping]

This is the kind of thing I was looking for. The use of comments within
<div> might be a problem as they can't be accessed via the DOM, right?
I'm not sure escaping the MathML or TeX is as big a problem as you say
as it can be handled by proper authoring tools.
