Not only that, but libxml2 is a rich source of security bugs.  I wish
we could get rid of that dependency altogether.  Unfortunately,
reimplementing our own xml and xpath functionality from scratch
seems like a large project :-(.  I don't think there's anybody
with sufficient time and interest to do it.
