I have for a while been irritated by the fact that HTML3 demands that
certain tags can only be used inside a <math> - container. Why can't I
write &lambda; anywhere where plain text (or other &--; -
constructions) is valid? According to the (expired) proposal nice
constructions like &ldots; (three dots at the baseline in text ie.
"...") must be enclosed in math - tags. This seems like an inheritance
from LaTeX (one of LaTeX's features I also despise) and I claim that
it is totally unnecessary and on the whole a nuisance for an author.

I propose that all &--; constructions be made valid anywhere inside
the scope of the <body> tag. There should be enough unique names for
all of these, and a specific tag should retain it's presenatation in
all contexts (except for font changes etc.).
	The prime example of this is Arena (beta1-e) which lets
&times; be represented by an 'x' outside of math mode, and by a
centered dot (^.^) in math mode. OK, this is an Arena bug, but the
fact that &cdot; and &middot; exist (and are supported by arena)
indicate that something needs to be done.
	&middot; (as far as I can see) is represented as ('mapped
to') a centered dot in all modes (inside <body>).
	&cdot; is from LaTeX and is mapped to a centered dot in math
mode, nothing outside.
	&times; as I said is represented ambiguously in arena - it
_should_ be a stylised 'x' in all modes.



Favorite Peeve:
A document that is used by a large number of people should _not_
expire until an adequate substitute exists. It is rubbish that the
HTML3 definition has expired, that is only a beaurocratic idiosyncrasy
and a damn nuisance!
