OpenDayLight Oxygen Netconf mount data-missing error - opendaylight

Question

I am using ODL oxygen release to connect a netopeer-server (NETCONF host) using the below curl command. I see the following error being returned. May I know what exactly is wrong? netopeer server supports netconf-monitoring.
{"errors":{"error":[{"error-type":"protocol","error-tag":"data-missing","error-message":"Mount point does not exist."}]}}

I did try the suggested changes. COuld you please tell me what is wrong with the input? I do not see anything obvious!
curl -H "Content-Type: application/xml" -u admin:admin -X PUT -d "<?xml version=\"1.0\" encoding=\"UTF-8\"><node xmlns=\"urn:TBD:params:xml:ns:yang:network-topology\">

This worked after adding the ? at to the xml tag as below
curl -H "Content-Type: application/xml" -u admin:admin -X PUT -d "<?xml version=\"1.0\" encoding=\"UTF-8\"?><node xmlns=\"urn:TBD:params:xml:ns:yang:network-topology\">

This seems like old way of mounting devices through config sub-system, can you try with this more recent API: http://docs.opendaylight.org/en/stable-oxygen/user-guide/netconf-user-guide.html#netconf-connector-configuration-with-md-sal
