Attributes with unknown tags should be treated as unknown
attribute types. Just like if a client asked for the name attribute
and got back cn, sn, givenName, and nickName, but did
not know anything about the nickName attribute. If a client
asks for cn and gets back cn and cn;lang-fr, it should just
ignore it (or display it - the client's choice, obviously).

X.500 does this with contexts (my understanding). I'd be
happy to see someone more familiar with X.500 define
what this mapping should be.                         -- Tim
