I'm not sure. Jimmy and Tatu have the interesting idea about Map<String,
int> and running an XPath from the int (node index). I like that! In my
case, it would be Map<int, int> with both ints non-objects using fastutils.

Do you think some thing as simple as this would be too simple for your
use cases?

Cheers.
