The rel- and rev-based microformats (e.g. rel-tag, votelinks, etc) can
be used validly as far back as HTML 2.0. But HTML 2.0 didn't include a
class attribute, so the bigger microformats can't be used.

I think the HTML 3.0 drafts included the class attribute, but HTML 3.0
faltered and never really happened. HTML 3.2 was published as a W3C
Recommendation, but didn't include class. (The DTD explicitly mentions
it as something that was omitted.)
