7.6. Also Note 2 needs to be removed from that table. In addition, in Annex C,

a technical corrigendum to this document commensurate with the proposed changes
to Space Link Identifiers above. In Section 2.2.2.2 CCSDS Packet Delivery
Service, we should remove the references to IPv4 and SCPS-NP and say ... (see
Table 7.6 of Reference 10, Space Link Identifiers Blue Book). Also need to
remove IPv4 from the acronym list. <o:p></o:p></span></font></p>

meetings to deprecate ISO 8473 from Table 5.2 Reserved APIDs in Space Link
Identifiers. The same action applies for agencies to do diligence to ensure it
is not used. In that spirit, reference [16] would also be removed from that
document. This change would be rolled into the change package for the
Space Link Identifiers BB. <o:p></o:p></span></font></p>
