Thanks for the tip--I haven't had a chance yet to look at the examples, but
I'll try to review it over the weekend. The release notes suggest that
XMLWidgets may address some of my issues.

After a little thought, the answer to my simplistic question above is that
XML documents may (often) have repeating elements at a given level of the
hierarchy. When that is the case, a url using element names will not be able
to target a unique location in the document. Duh.

It would still be interesting to consider using node ids that are a bit more
informative than the current ones. Say, the tag name concatenated with the
numerical position of the tag in the sequence of similar tags at that level.
