can you point me at any call in libxml2 which will evaluate an xpath

apart from anything else, xpath requires there to be a (single)
context node (see http://www.w3.org/TR/xpath20/#context ). For a doc,
we set that node to the document node, but what would it be for a
node-set or a fragment? If we can't get over that hurdle we're
screwed in pursuing your line of thought.
Which may hint at the fact that running xpath on content fragments is
ill-defined to begin with?!?
Right. But that's no excuse for what we have been doing, which was
demonstrably providing false results on good input.
