Well I never could imagine that when you write "reasonable xml syntax" you
can mean XML, SGML, or even HTML. Sorry, I have not developed telepathic
capabilities yet.

Machine generation of the kind is usual in MathML, SVG... no problem here:

LaTeX ==> p-MathML

LaTeX ==> abspos-CSS

I have seen CSS techniques for matrices without composed brackets not
scaling of single characters. What is the problem here?

This appeal to TeX quality is really odd. The web is not about visual
quality (the ppp of best monitors is very inferior to any average
printer). The web is about content, online access to remote information,
multimedia, and hipertext. First fulfill those requirements and then focus
on TeX visual quality.

It is very amazing to read the repeated mantra about the (claimed) virtual
TeX quality achieved by MathML for online mathematics, whereas is
sistematically ignored that qualities for aural rendering, "semantics",
and structural markup of the MathML code one get from the web each day are
so low that very old approaches as HTML 3 can do often a better work.
