Drat. I was on the verge of coming out in favor of pid.
Of all the options, path id made the most sense, if id
is going to be used at all.

Ontologically, speaking, though, I don't like the use
of "id" because "id" suggests a 1:1 mapping. There are
many paths to a single node, however. That many:1 mapping
is inconsistent with the XML notion of "id" as a unique

Personally, I'd go with "nid" and "path".
