  This should be safe as long as none of the XPath expressions need to
access the root, but this is a non-common situation so you are exposing
yourself to potential bugs that may have been unnoticed because everybody
tests with document where all nodes refers to a doc.
  I can't give a formal "this is safe" statement.
