   // Constants that define which usages a certificate is trusted for.

   // of certificate.
   // For a CA_CERT, they specify that the CA is trusted for issuing server and
   // client certs of each type.
   // For SERVER_CERT, only TRUSTED_SSL makes sense, and specifies the cert is
   // trusted as a server.
   // For EMAIL_CERT, only TRUSTED_EMAIL makes sense, and specifies the cert is
   // trusted for email.
+  // DISTRUSTED_* specifies that the cert should not be trusted for the given
+  // usage, regardless of whether it would otherwise inherit trust from the
+  // issuer chain.
+  // Use TRUST_DEFAULT to inherit trust as normal.
   // NOTE: The actual constants are defined using an enum instead of static
   // consts due to compilation/linkage constraints with template functions.
