That's what Level 3 is all about. If it has a theme, it's "filling in the
obvious holes" such as DTD support, and load and save.

The DOM WG has done its best to design the DOM to be usable
as the basis for such layering. And, for example, MathML, SMIL
and SVG are all doing DOM modules fo ruse on top of the basic
DOM. XPath would be a module no matter who did it; the only
question is who should do it. I personally think it should be the
people with experience in the matter, e.g. it's the SVG WG doing
the SVG DOM, not the DOM WG.
