I was thinking that we should include something like:

The pair of newly defined SDP 'tls-id' attribute values from the offer and
the corresponding answer can be used to uniquely identify TLS or DTLS
association. This unique identifier can be used by TLS protocol extensions
to differentiate between multiple TLS and DTLS association and correlate
these associations with specific offer/answer exchanges.
