I agree with Khalid,
   and at the same time I feel that there is lack of agreement on the use of terms
- describe
- represents

which I suspect is ultimately just a matter of terminology rather than of deep substance.
I suggest that a specific issue on this be raised against the doc, as it makes it sooo much easier to follow it (at least for me).

Thanks, -Paolo
