[atlas] REST API Problems for DNS measurements with DO and TCP

Hi! I managed to create DNS measurements via the REST API, but fail to 
set the DO and protocol:TCP option. According to the documentation 
(https://atlas.ripe.net/doc/measurement-creation-api/) the relevant 
properties are use_EDNS0 and use_tcp. So I tried it with

{
         "definitions": [
                 {
                         "is_public": true,
                         "is_oneoff" : false,
                         "target": "194.0.25.13",
                         "description": 
"a.dns.nic.versicherung_IP4_TCP_noDO",
                         "type": "dns",
                         "af": 4,
                         "interval": 300,
                         "use_EDNS0": false,
                         "use_TCP": true,
                         "use_probe_resolver": false,
                         "use_NSID": true,
                         "query_class": "IN",
                         "query_type": "SOA",
                         "query_argument": "versicherung",
                         "udp_payload_size": 1024,
                         "protocol": "TCP",
                         "do": true
                 }
         ],
}

but that does not work - the generated measurements do not use TCP and 
DO. When I create the measurement via the web interface and review the 
measurement via the REST API, I see that other properties are set: "do" 
and "protocol". E.g:

# curl https://atlas.ripe.net/api/v1/measurement/1027747/
{"all_scheduling_requests_fulfilled": true, "can_visualise": false, 
"creation_time": 1380018470, "description": "TEST via WEB", "do": true, 
"dst_addr": "194.0.25.13", "dst_asn": "1921", "dst_name": "194.0.25.13", 
"interval": 240, "is_oneoff": true, "is_public": true, "msm_id": 
1027747, "nsid": true, "participant_count": 1, "protocol": "TCP", 
"query": {"class": "IN", "type": "SOA", "value": "versicherung."}, 
"resolve_on_probe": false, "resolved_ips": ["194.0.25.13"], "result": 
"/api/v1/measurement/1027747/result/", "start_time": 1380018470, 
"status": {"id": 7, "name": "Failed"}, "stop_time": 1380018904, "type": 
{"id": 6, "name": "dns"}, "udp_payload_size": 512}

So I tried to create measurements with the "do" and "protocol" 
properties, but these properties are again ignored.

If I am doing something wrong, so please give me some hints. Otherwise 
the API documentation is wrong and these properties can not be set via 
REST, only via the web interface - and should be fixed.

Thanks
