    18   These fields MUST only appear if the version is 2 or 3 (Section 4.1.2.1).
    19   These fields MUST NOT appear if the version is 1. The subject and issuer
    20   unique identifiers are present in the certificate to handle the possibility
    21   of reuse of subject and/or issuer names over time. This profile RECOMMENDS
    22   that names not be reused for different entities and that Internet certificates
    23   not make use of unique identifiers. CAs conforming to this profile MUST NOT
    24   generate certificates with unique identifiers. Applications conforming to
    25   this profile SHOULD be capable of parsing certificates that include unique
    26   identifiers, but there are no processing requirements associated with the
    27   unique identifiers.
