+        This is useful when the remote FIX engine does not allow to ask for more than n message for a ResendRequest. It also allows you to prevent a 'self-DDOS' by accidentally requesting a huge flood of messages your system isn't capable of processing if you are substantially behind for some reason.
         <P>
          E.g. if the ResendRequestChunkSize is set to 5 and a gap of 7 messages is detected,
          a first resend request will be sent for 5 messages.
