Keep 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.

This keeps the primacy of place for DTDs as the foundation of XML in theory while largely ignoring their existence in practice.

Elliotte is right. The DTD formally ensures that well-formedness is not the
single possible basis of acceptance of an XML instance.  Preferences for how
that is documented seem to break down when describing why that is necessary.

No, I don't think that's sufficient. FDTDs are fundamentally
integrated into the design of an XML parser. They are not optional
pieces one can ignore. Nor are they just a schema language either.
They have noticeable effects on a document's infoset even in the
absence of validation. Yes, in hindsight, this was a mistake; but it's
not one we can ignore or sweep under the rug, much as we might wish
things were otherwise. :-(
