There have been several proposals over the years for updating DTDs, with
varying levels of obscure or arcane syntax.  But none of the proposals
seems to have clear benefits over W3C XSD, or even over RNG, and the
cost of changing DTDs could potentially be very high in terms of
interoperability.

I don't see that changing as a result of HTML 5.

On the other hand, DTDs are the only way (today) to declare text
entities, and are useful for simple syntax checking, so I also don't see
them going away any time soon.
