Should only encode containers with some data

Current Behavior

Encoding containers with no data. For example, <ipv6/> is showing up below

Your Script

self.ping = Cisco_IOS_XR_ping_act.Ping()
self.input = self.ping.Input()
self.destination = self.input.Destination()
self.ping.input.destination.destination = '1.2.3.4'
self.ping.input.destination.timeout = 1
self.execn_rpc = ExecutorService().execute_rpc(self.provider,self.ping)
