That's a silly statement.

Not following SHOULDs, unless there is a very good reason, is bad.

Photo-ID and what else? Nothing. And the photo ID breaks nothing, either. Packet 17 is unused. If it were assigned to something else, and there was a conflict there, then things would be broken. The fact is the WG was told about the photo ID, and in my opinion should have made allowances for it. (The proposal was for a "biometric data packet" that could contain things like photos, fingerprints, voice-prints, etc.) And, if you follow the suggestion of the draft: However, if an implementation wishes to be compatible with such keys, the packet may be considered to be a user id packet with opaque contents. (As GnuPG does, I believe -- or does it just trim them from the key?), PGP keys play happiliy with GnuPG. - --Len. __ L.
