This document define a new form of name, called permanent identifier, that
may be included in the subjectAltName extension of a public key certificate
issued to an entity. The permanent identifier is an optional feature that
may be used by a CA to indicate that the certificate relates to the same
entity even if the name or the affiliation of that entity stored in the
subject or another name form in the subjectAltName extension has changed.
The subject name, carried in the subject field, is only unique for each
subject entity certified by the one CA as defined by the issuer name field.
Also, the new name form can carry a name that is unique for each subject
entity certified by a CA.
