+that we trust to sign other certificates.  Note that for a CA to be
+really trusted, it needs to be somehow referred to by policy, in

+The certificates in this directory are used for the actual X.509
+authentication and for cross-referencing policies that refer to
+Distinguished Names (DNs). Keeping a separate directory (as opposed
+to integrating policies and X.509 CA certificates) allows for maintenance
