	I don't know how you are using the term "official", nor want
to get into a semantic debate about it. :) :)

	I was assuming that Peter would offer his composite DTD for
public discussion by all interested persons, and would amend it
toward some consensus of what would be most useful to as many of
those interested persons as possible, as well as making his own
judgements based on his expertise in SGML.

	I don't see why the current two validation services would
object to including a DTD developed in that way, together with the
others they support.

	A lot of what will be "restored" in it was designed to
degrade gracefully for clients which do not support it.  But
using it is presently problematic with respect to validation
if you also use markup developed since, and not in, the (expired)
HTML 3.0 DTD.
