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.
