Thanks, now I understand this better. So does this wording describe
the situation correctly:

   This is achieved for "turn" URIs by the Long-Term Credential
   Mechanism defined in [RFC5389], which is mandatory for TURN
   [RFCxxx]. For a "turns" URI, the usage of TLS addresses the
   requirement."

Having both references would have helped me to understand the
situation better (showing my ignorance of TURN ;-).
