Audience considered, DTD’s aren’t the basis for XML. IMO, they are a system device from SGML that XML carried over in context of the singular specification itself. At the time, they ensured validation as a system feature would be preserved until other means were formulated and formally published. It bridged a perceived chasm.
So a decision made in a time for the needs of that time. Still relevant? I dunno. The usual cliché is you never know how used or useful a feature is in a standard until you try to take it out.

in mind audience here. I'd be inclined rather to indicate that an XML document
is a valid SGML document as well, that for this reason there is an implicit
assumption that a DTD exists for any created XML document type, but that
current usage is increasingly to keep such DTD's implicit in favor of more
explicit definitions by other schemas. On Fri, Aug 21, 2009 at 4:52 PM, Len Bullard <cbullard@hiwaay.net> wrote: Elliotte is right. The DTD formally ensures that
