Hi Charles,

Thanks for your comments! I will implement all but 6) as suggested.

Regarding 6), it is not forbidden to use the 'connection' attribute in the m- line if it is used for something else than the DTLS connection. The subsequent paragraph gives an example of SCTP usage with DTLS.

But, I can combine the paragraphs, and modify:

"This specification does not define the usage of the SDP 'connection' attribute [ref] for negotiating a DTLS connection. However, the attribute MAY be used if the DTLS connection is used together with another protocol, e.g. SCTP or TCP, for which the usage of the attribute has been defined."

Regards,

Christer
