HTML *is* SGML. It is impossible to properly parse HTML documents without
reference to the SGML standard.

That is like suggesting that in this mailing list we are going to use a
subset of English, but not necessarily English semantics for words.

Certainly. But it is 

 a) not clear that this will always be the case (i.e. HTML 4.0 will be
viewable on an HTML 1.0 browser)

 b) clear that other non-HTML tagged data formats will become common on the
Web (look at W3Cs Technical Reports page)

 c) always better for a user agent to have more information, instead of
less, on the author's intended meaning of the document. Did they want to use
Netscape's EMBED tag, or W3Cs, for example?

An HTML parser has the option of ignoring <!...>. That does not make it a
comment. If it were a comment, <! This is a comment > would be valid (which
it is not).

Life is hard. Metadata is necessary.
