      public class SendingRenewal
      extends SendingSync<OutgoingRenewalRequestMessage,IncomingSubscribeResponseMessage>

  Renewing a GENA event subscription with a remote host.

  This protocol is executed periodically by the local registry, for any established GENA subscription to a remote service. If renewal failed, the subscription will be removed from the registry and the `RemoteGENASubscription.end(org.fourthline.cling.model.gena.CancelReason, org.fourthline.cling.model.message.UpnpResponse)` method will be called. The `RENEWAL_FAILED` reason will be used, however, the response might be `null` if no response was received from the remote host.
