#153: Section 2.8 Access-Info

 The Access-Info Attribute is utilized by implementations of
       IEEE-802.1X [IEEE-802.1X] to specify the Access status information
       field within an Access Information Type Length Value Tuple (TLV)
       to be sent to the user within MACsec Key Agreement (MKA) or EAPoL-
       Announcement frames.

       A single Access-Info Attribute is permitted within a RADIUS
       Access-Accept, Access-Challenge, Access-Reject or Accounting-
       Request packet.

 [BA] The above paragraph seems to imply that the Access-Info Attribute
 could cause the Access status information to change during and after
 authentication.  It is unclear how supplicants would respond to such a
 change.  For example, the potential response to a change in MKA (which is
 authenticated) could be quite different from a change in an EAPoL-
 Announcement frame (which is not).  As a result, the desired behavior is
 unclear.
