Section 2.2 says:

   The purpose of this attribute is to make it possible to link together
   multiple related sessions.  While [IEEE8021X] does not act on
   aggregated ports, it is possible for a Supplicant roaming between
   Access Points to cause multiple RADIUS accounting packets to be sent
   by different Access Points.

It should say:

   The purpose of this attribute is to make it possible to link together
   multiple related sessions.  While [IEEE8021X] does not act on
   aggregated ports, it is possible for a Supplicant roaming between
   Basic Service Sets to cause multiple RADIUS accounting packets to be
   sent by the same or different Access Points.

Notes:

This was written in the context of an Access Point only offering a single Basic Service Set, predating Access Points containing multiple radios or supporting Virtual Access Points. It is not accurate today.
