I thought Michael Kay mentioned on the list not too long ago that it was
in fact a misreading to ever think that a result tree fragment was false,
because it always contains a root node and it is, according to the spec,
always treated like a node-set. Unfortunately the error wasn't discovered
in time for his book going to press. I wish I still had the post I am
thinking of...
