That's only part of the problem though. Namespaces are also nasty,
and that's purely DOM's fault. I can use namespaces to produce a
document that can't be serialized without any DTD. And it possible to
avoid this. JDOM and XPath 1.0 both do not allow the namespace
declarations to get out of sync with the namespaces actually used.
