Comments in particular are one of the places where SGML said one thing, the
HTML spec which was loosely derived from SGML said a different thing, and
most browsers did (occasionally mutually incompatible) something not quite
either, with the result that they can be *very* difficult to get right in
the general case.
HTML is not at all easy to deal with.
