I believe /doc/point() (and thus /doc/point()[2]) yields an empty
location-set regardless of the document. The second step is an
abbreviation of child::point(), the 'child' axis can contain only nodes,
and the 'point()' test is false for all of them, so the result is an
empty set.

So xpointer(/doc/point()[2]) always has a sub-resource error.
