i read this in the short descriptions which i found online, but i'm
sceptical about it. other tagging methods whould have been sufficient to
achieve the same ends with pointers.
has there been any experience with the matching costs against data
objects more complex than a few items out of a single relational dataset?

i would wonder whether one has implemented xml pointers for this with
yet another encoding...
