This was explicitly out of scope from the former OpenPGP WG.  I think
that was a GOOD THING, and I believe it should remain out of scope.
IMHO we shouldn't define how OpenPGP is used, only what it inputs and
outputs.

For the record, draft-atkins-openpgp-device-certificates already extends
the Attribute Subpacket with a String ID (similar to the UserID).
