Good point, If the TURN server is configured with multiple realms, it might
want to respond all realms it supports (multiple realm attributes), or it
might respond some special meaningful realm then the client can get help
out of band, or just randomly pick one, etc...
The problem 1 and 2, listed in the draft is very common. Implementers are
easy to get missed without a clear guidance.

Thanks,
Wilson Chen
