I think you'll find that guidance in the next update of 3734bis.  Two
IESG members have said that the document needs text to require use of
the certificate subject as part of the authentication process.  I hope
to have the final version ready for IESG approval in the next day or so.
I'm just waiting for one IESG member to confirm that the changes are
acceptable.
