I've updated the above to use subpacket ID 36 for "Designated Revoker"
instead of 35, since 35 is already in use in the wild by the "Intended
Recipient Fingerprint" subpacket in at least two implementations i'm
aware of.  (see message-id: 20180305231951.GA21944@calamity from
2018-03-05 on this mailing list, and subsequent discussion)

I've opened https://gitlab.com/openpgp-wg/rfc4880bis/merge_requests/19
to track the "Intended Recipient Fingerprint" subpacket.
