        I'm not quite sure that this attribute is appropriate.

        From its description below it's clear that this attribute is to
        hold references to the entries corresponding to the real-world
        objects that are (somehow) related to the given real-world
        object.  The attribute I had in mind is either more specific or
        (if ``related'' is specifically prohibited from carrying the
        meaning ``being the same'') completely different.

        Therefore, using `seeAlso' in such a way would, at least,
        confuse potential users of the data.

2.30.  'seeAlso'

   The 'seeAlso' attribute type contains the distinguished names of
   objects that are related to the subject object.  Each related object
   name is one value of this multi-valued attribute.
   (Source: X.520 [X.520])

      ( 2.5.4.34 NAME 'seeAlso'
         SUP distinguishedName )

...

   Example: The person object "cn=James Brown,ou=employee,o=Widget\,
            Inc." is related to the role objects "cn=Football Team
            Captain,ou=sponsored activities,o=Widget\, Inc." and
            "cn=Chess Team,ou=sponsored activities,o=Widget\, Inc.".
            Since the role objects are related to the person object, the
            'seeAlso' attribute will contain the distinguished name of
            each role object as separate values.
