Not the individual parts strings deimited by slashes are unique, but the 
URL as a whole is.

_make_id() makes sure there are no two elements with the same URL, it does 
so by making sure there are no two elements with the same id on one level 
of the URL.

e5/e5/e17 addresses one element only, e5/e5/e18 another. So does e6/e5/e17.
