                   IANA Registry Updates for OpenPGP
                 draft-openpgp-iana-registry-updates-02

Abstract

   This document describes a number of changes to the OpenPGP (RFC 4880)
   IANA registries that range from adding notes to the registry to
   changing registration policies.  These changes were motivated by
   recently proposed extensions to OpenPGP.  Existing IANA OpenPGP
   registry policies are defined by RFC 4880.
