Um, why would it mean that? The example you gave, of <input
type='...'/>, has no content, so there's not much to constrain. Some
of the other attributes on <input> are type-specific, but neither SGML
nor XML DTDs allowed you to constrain those either -- the only
constraints are provided in the prose of the REC. There is already
a W3C XML Schema which reconstructs the DTD for XHTML [1]
Are you thinking of schematron rules for those attribute-interaction
constraints?
