The current HTML document is both a descriptive spec and a text/html
specification. Well... at least that's what I was thinking, unless we
want to hold off the text/html registration until 2.1 or whatever.
As to future HTML versions, Dave Raggett et. al. are furiously busy
with an HTML 3.0 draft spec and implementation.

Discussions of more modest revisions of HTML, loosely dubbed 2.1, have
occurred on this list recently. Internationalization seems to be the
hot topic.
