I think 'longer' is not a precise term ... likewise, 'more specific' isn't
precise enough to avoid confusion. I think what would be expected is that
the path sith the most 'levels' (as noted by '/' characters) is longer in 
a deeper into the hierarachy sense. Same depth, the age rule could apply.

If 'more specific' is already defined similar to what I've outlined,
you can igore this comment.
