I'm not sure what *new* standard you are refering too.  Within the OIW these
addresses have been agreed to for some time.  I'm not sure if they are in
the TA ISP for token ring, I thought that they were.

Below is the relevant text from the OIW stable agreements.

          Part 3 - Network Layer                        March 1991 (Stable)

               12.2.1.4 of ISO 10039;

               i)  The multicast addresses corresponding to "All
               Intermediate Systems on the Network" (ALL_ISN) and "All End
               Systems on the Network" (ALL_ESN) shall default to the
               following on IEEE802.3 and IEEE802.4 subnetworks:

                    1)  ALL_ESN = 09-00-2B-00-00-04, ALL_ISN = 09-00-2B-00-
                    00-05;

                    2)  It is understood that the hexadecimal octets shown
                    are transmitted onto the medium from left most octet to
                    right most octet. Within each hexadecimal octet the
                    least significant bit is transmitted first;

               j)  The multicast addresses corresponding to "All
               Intermediate Systems on the Network" (ALL_ISN) and "All End
               Systems on the Network" (ALL_ESN) shall default to the
               following two functional addresses on IEEE802.5 subnetworks:

                    1)  ALL_ESN = C000 0000 4000, ALL=ISN - C000 0000 8000;

                    2)  It is understood that the hexadecimal octets shown
                    are transmitted onto the medium from left most octet to
                    right most octet. Within each hexadecimal octet the
                    most significant bit is transmitted first;


               Editor's Note - Note that in the hexadecimal representation
               defined in ISO 10039, these addresses would be:
                    1)  ALL_ESN = 03-00-00-00-02-00

                    2)  ALL_ISN = 03-00-00-00-01-00


               NOTE - This notation presents the octet values such that the
               least significant bit is that transmitted first.

               k)  The Error Report flag shall be set to zero (0) for NPDUs
               sent as a result of invoking the QUERY Configuration
               Function.

               l)  ISO 8473 PDUs multicast as a result of the Query
               Configuration function shall use the Network Layer Protocol
               ID (NLPID) assigned to ISO 8473.

               m)  An ISO 8473 PDU received as a result of another ES
               having performed the Query Configuration function shall be
               processed as follows:
