-// avoid an awkwardly long type name.
-// The type is a combination of intrinsic properties, such as the presense of an
-// Certificate Authority Basic Constraint, and assigned trust values.  For
-// example, a cert with no basic constraints or trust would be classified as
-// UNKNOWN_CERT.  If that cert is then trusted with SetCertTrust(cert,
-// SERVER_CERT, TRUSTED_SSL), it would become a SERVER_CERT.
