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.
