/** This is the control provider outlined in PEP#187 SSL Certificate Mgmt Enhancements.
 * It models certificate mgmt operations as standard CIM operations.  Client certificates are modeled
 * by the PG_SSLCertificate class. Certificate revocation lists (CRLs) are modeled using the 
 * PG_SSLCertificateRevocationClass.  These classes are defined in the pg_internal schema.  
 * The ssltrustmgr CLI in Clients/ssltrustmgr can be used to invoke these provider methods.
