In way of explanation, I'm going to go out on a limb and make an educated guess that
there's a generic mechanism warning about the use of internally used attributes
in the filter module, as those attributes have no representation on the wire, and
that there turned out to be a use case for internally handling Access-Reject packets
(it would seem these are timing parameters, so something to do with DoS/flood protection
or a keepalive mechanism.)  This ended up passing these attributes through
the attribute filter module, so they were exempted as a quick fix rather than
specially handling the internally handled packets.
