+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+* ``crl_all_reasons.pem`` - Contains a CRL with 12 revoked certificates, whose
+ serials match their list position. It includes one revocation without
+ any entry extensions, 10 revocations with every supported reason code and one
+ revocation with an unsupported, non-critical entry extension with the OID
+ value set to "1.2.3.4".
+* ``crl_dup_entry_ext.pem`` - Contains a CRL with one revocation which has a
+ duplicate entry extension.
+* ``crl_md2_unknown_crit_entry_ext.pem`` - Contains a CRL with one revocation
+ which contains an unsupported critical entry extension with the OID value set
+ to "1.2.3.4". The CRL uses an unsupported MD2 signature algorithm.
+* ``crl_unsupported_reason.pem`` - Contains a CRL with one revocation which has
+ an unsupported reason code.
