And with direction you mean what?

We have no abstract direction between links.

A --linked to-- B

..and now we know B is --linked to-- A but what's the abstract direction 
between them? Yes, there are no abstract direction always needed but..

Let's say:

Adam is linked to Benja.
Adam is father of Benja and of course
Benja is Adam's son.

What we see in xupdf is that
Adam is linked to Benja.

If we write to the link: "father of" we still don't know the abstract 
direction. So we don't know if
Adam is father of Benja or Benja is father of Adam.

So linking doesn't tell the abstract meaning between links.
