Insofar as DTDs are used to describe content models and attribute information,
I agree.  It is very slick to take a stand-alone DTD, convert it to RNG
with DTDinst (which carefully preserves readability), and then use Jing
to validate against incoming documents.

DTDs for entities and other such things are probably dying.
