Hi,
   I feel BFCP over DTLS is not well documented in rfc4582bis.
  At section 7 "Lower-Layer Security".
It says "BFCP floor control servers
   and clients MUST support TLS for transport over TCP and MUST support DTLS for
   transport over UDP [4]." But reference [4] is only about  BFCP over TLS.
Reference for BFCP over DTLS seems missing.
At the end of the same section,it seems say DTLS connection setup
procedure shall
follow [7].  If it is true, does it mean BFCP message is packeted as
SRTP? If not, would it be better to
give more details about DTLS connection setup and packetization.

  Please give more explain.

Thanks in advance,

Youngmin
