           description
             "Container for all operation resources.
              Each resource is represented as an empty leaf with the
              name of the RPC operation from the YANG 'rpc' statement.              

              For example, the 'system-restart' RPC operation defined
              in the 'ietf-system' module would be represented as
              an empty leaf in the 'ietf-system' namespace.  This is
              a conceptual leaf and will not actually be found in
              the module:

                 module ietf-system {
                   leaf system-reset {
                     type empty;
                   }
                 }

              To invoke the 'system-restart' RPC operation:
                 POST /restconf/operations/ietf-system:system-restart

              To discover the RPC operations supported by the server:
                 GET /restconf/operations

              In XML, the YANG module namespace identifies the module:
 
               <system-restart
                   xmlns='urn:ietf:params:xml:ns:yang:ietf-system'/>
 
             In JSON, the YANG module name identifies the module:
 
               { 'ietf-system:system-restart' : [null] }
             ";
         }
