... and constantly adding more functionality to it is the "bloat"
to which I referred.  The point's been raised that some of the
current functionality might well be completed, before adding any
newer functionality.  (Everything DTD-related is incomplete, since
one can't start with an empty DOM tree and add those functionalities
without requiring proprietary extensions.)

There's a concept called "software layering" that I adhere to -- I'm
sure you know it well.  Modules can use DOM without being bundled into
DOM itself.  XPath can (and IMHO should) be such a layer.
