+// According to the Baseline Requirements version 1.3.3 section 7.1.4.2.2.a,
+// the requirements of the subject common name field are as follows:
+// "If present, this field MUST contain a single IP address or Fully‐Qualified
+// Domain Name that is one of the values contained in the Certificate’s
+// subjectAltName extension". Consequently, since any name information present
+// in the common name must be present in the subject alternative name extension,
+// when performing name matching, it should not be necessary to fall back to the
+// common name. Because this consequence has not commonly been enforced, this
+// implementation provides a mechanism to start enforcing it gradually while
+// maintaining some backwards compatibility. If configured with the mode
+// "EnforceAfter23August2016", name matching will only fall back to using the
+// subject common name for certificates where the notBefore field is before 23
+// August 2016. Similarly, the mode "EnforceAfter23August2015" is also
+// available. This is to provide a balance between allowing preexisting
+// long-lived certificates and detecting newly-issued problematic certificates.
+// Note that this implementation does not actually directly enforce that if the
+// subject common name is present, its value corresponds to a dNSName or
+// iPAddress entry in the subject alternative name extension.
