Well, I'd still like Comment, PI etc to have getParent() also.
Of course, the problem there is parent can be a Document or an
Element.

Since those are wacky, I can certainly work around them on my own,
should JDOM not include support.  I don't see that as too much of
a show stopper.  But XPaths involving attributes will probably
occur often enough (in XSLT, if nothing else) to warrant (in my
mind) explicit support from JDOM itself.
