I agree.  It seems to me that each will get used where considered
pragmatic.  From my point of view, I'd be likely to continue to use
DTDs for "document" applications, whereas I'd use schemas for "data"/
application interaction scenarios, where the added tightness is much
needed, and will enable better tool support.

DTDs can be built by hand, but it looks like tool support will be needed
to build complex Schemas.
