Since HTML 3.2 predates the standards that we are attempting to support (CSS and
HTML4, to be exact), we should _not_ be rendering HTML 3.2 documents in
standards mode (since they will break unless the author is posessed of a great
deal of prescience).  The point of quirks mode is to deal with pages written
before the current standards existed; doctype sniffing is just an attempt to
estimate the time when the page was written (this is why HTML 4.01 and HTML 4.0
are treated a little differently).

See http://www.mozilla.org/docs/web-developer/quirks/doctypes.html for more
information on the topic.
