No no no -- this is completely not the case!  I was the one
arguing for a more semantic basis for representation on the
HTML-Math mailing list way back when they were doing a kind
of LaTeX-Mathematica-derived syntax, and others were reluctant.

MINSE is a structured expression notation completely separate
from the presentation which can be specified in a stylesheet.
It was actually kind of a precursor to XML, but without the
hype, with a more concise and readable syntax, and with a more
convenient and powerful stylesheet mechanism.

It's nice, but i'd still much rather type "5 < x <= 10".
