[Med] What about making this change: 

OLD:
      *  Description: This Information Element contains the maximum
         number of IP source transport ports that is a limit for an end
         user to use and is associated with one or more IPv4 or IPv6
         addresses.

NEW:
      *  Description: This Information Element contains the maximum
         number of IP source transport ports that can be used by an end
         user when sending IP packets; each user is associated with one
         or more (source) IPv4 or IPv6 addresses.  This IE is
         particularly useful in address sharing deployments that adhere
         to REQ-4 of [RFC6888].  Limiting the number of ports assigned
         to each user ensures fairness among users and mitigates the
         denial-of-service attack that a user could launch against other
         users through the address sharing device in order to grab more
         ports.
