Minidom and pxdom both support the DOM Level 3 Core ID functionality
(Attr.isId, Element.setIdAttribute etc.), and will automatically make an
attribute have IDness when it is added to a document whose DTD states
that element+attribute is of type ID.

Not to my knowledge. Minidom maintains a cache of previously-looked-up
IDs, but that's internal and not really what you want. Assuming you're
manipulating the document with DOM tools, there's probably no shortcut
to just walking the entire document noting the value of every attribute
where Attr.isId is True.
If you're just checking each IDREF attribute matches something, is the
test 'document.getElementById(idrefAttr.value) is not None' too slow?
