The "rev" parameter has been used in the past to indicate that the semantics of the relationship are in the
reverse direction.  That is, a link from A to B with REL="X" expresses the same relationship as a link from B to
A with REV="X". "rev" is deprecated by this specification because it often confuses authors and readers; in most
cases, using a separate relation type is preferable.
