It's, well, missing. The body of the method, that is (in Squeak
3.3a-4771). Such missingostiy breaks all the #tag(s)Named methods.

I see it's implemented in XMLElement, but then there should but a self
subClassResponsibility in the XMLNode version, yes? (And is there any
reason for this *not* to be working in XMLDocument?)

I'm liking the XML functionality so far, at least for the simple task I'm
working on.
