An editorial comment on Section 2.

Section 2

   Status-Server packets are sent by a RADIUS client to a RADIUS server
   in order to test the status of that server.  A Message-Authenticator
   attribute MUST be included so as to provide per-packet authentication
   and integrity protection.  A single Status-Server packet MUST be
   included within a UDP datagram.  RADIUS proxies MUST NOT forward
   Status-Server packets.

   Since a Status-Server packet MUST NOT be forwarded by a RADIUS proxy
   or server, the destination of a Status-Server packet is set to the IP
   address of the server which is being tested.  As a result, the client
   is provided with an indication of the status of that server only,
   since no RADIUS proxies are on the path between the RADIUS client and
   server.  Since servers respond to a Status-Server packet without
   examining the User-Name attribute, the response to a Status-Server
   packet cannot be used to infer any information about the reachability
   of specific realms.

   A RADIUS server or proxy implementing this specification SHOULD
   respond to a Status-Server packet with an Access-Accept
   (authentication port) or Accounting-Message (accounting port).  An
   Access-Challenge response is NOT RECOMMENDED.  An Access-Reject
   response MAY be used.  The list of attributes that are permitted in
   Status-Server and Access-Accept packets responding to Status-Server
   packets are provided in the Section 6.

[BA] These three paragraphs are a bit disjoint.  Recommend changing it
to the following:

   a Status-Server packet is set to the IP address of the server that
