  Well, that's not exactly it either.  We could easily write *a* DTD
for it, if we're willing to restrict the prefixes.  But that wouldn't
be the same as letting the users pick an *arbitrary* DTD and make the
results conform to that -- we'd have to pick some W3C HTML DTD.  Well,
we could get fancier and have modified versions of all of them, and
re-write the DOCTYPE declaration on the way out (actually a relatively
reasonable way to do this), but I suspect some of the authoring tools
would have difficulty understanding the use of different doctypes for
editing.
  This is one of those cases where well-formed XML is the right thing,
and monkeying around with validation for intermediate forms is just
distraction.  Adding an option to remove the METAL/TAL attributes from
the output allows the result of transformation to be valid, and I
suspect that's what people really care about.

  And *that's* what's really important!
