Implement a new configuration definition called "TopCfgDefn" which acts as the parent of all other configuration definitions. This is analogous to the the "top" object class in LDAP.
The principle use of the TopCfgDefn is to make it easier for applications to determine all the possible types of managed object the administration framework supports.
The TopCfgDefn is not generated automatically from XML. Instead it is located in the org.opends.server.admin package together with the base client-side and server-side interfaces (ConfigurationClient and Configuration respectively).
