We aren't using circular refs in our DOM, so we don't have any way to
release a DOM object - losing or deleting the reference should do it.

If this isn't happening when the reference is going away, then this is
either a Zope bug or a ParsedXML bug.  I'd like to make sure that the
ref really is going away, though :)

Acquisition is what we're currently using to avoid circular
references.
