restricting search to different nodes

[David Carlisle]

  Is it somehow possible to adjust the return statements in that it treats the
  results differently if they come from different node sets?


yes, you just need to write the path so it works in either case, eg

return ancestor::text[1]

or if your system makes things inconvenient by not providing ancestor::
axis then

return
(self::abstract|self::metadata1/..)/../..
