Then, there are such expressions as Ga_(x)Al_(1-x)As,
where the amount of Ga and Al totals 1.
(I didn't check to see whether those are the correct HTML tags, btw.)

This surely does seem to be getting into the matter of Unicode's
definitions, versus rendering details independent of Unicode. At the
moment, I'm thinking that including super and sub numerals was a
"concession" or a convenience that does not strictly follow Unicode's
primary intent; might well be wrong on that.
