What Dimitri said, but to address your comment directly, DTD-based
validation is long-dead, at least when applied to HTML.  A DTD can't
capture the validity requirements that the HTML spec already imposes,
so it's irrelevant if it also can't validate a document containing
custom elements.  The current validator used by the W3C is a
combination of (iirc) constrains expressed in Schematron and custom
Java code.
