If having TCP peers is not important, then remove RFC 6062 from this draft.

Also, the draft does not explain the procedures related to SRV and NAPTR RRs:

example.net.
IN NAPTR 100 10 "" RELAY:turn.ws "" websocket.example.net.

websocket.example.net.
IN NAPTR 100 10 S RELAY:turn.ws "" _turn._ws.example.net.

_turn._ws.example.net.
IN SRV   0 0 80 a.example.net.

a.example.net.
IN A     192.0.2.1
