If the endpoint wants to modify its identity assertion within the session, it MUST include an 'identity' attribute value with the new identity assertion in the offer or answer. If the endpoint maintains or modifies its identity assertion within the session, it includes one or more SDP 'fingerprint' attributes. The set of fingerprints MUST be the same as the set to which the identity assertion is bound. If the endpoint wants to revoke its identity assertion from the session, it MUST NOT include an 'identity' attribute in the offer or answer. Specific usages might restrict the modification and/or revoking of the identity assertion within a session.  Endpoints can add, modify, or remove 'fingerprint' attributes when modifying a session.

Reviewer comments:
NAME I looked at the deletion issue and I don't think it's worth leaving it in as an exception, because you'd have to DTLS re-handshake anyway.

Revised text:
When an offerer sends an offer, in order to provide its identity assertion to the peer, it includes an 'identity' attribute in the offer.  In addition, the offerer includes one or more SDP  <ins> 'fingerprint' attributes.  The 'identity' attribute MUST be bound to all the 'fingerprint' attributes in the session description. </ins> 5.1.2. 5.1.5.  <ins> When modifying a session, if the set of fingerprints is unchanged, then the sender MAY send the same 'identity' attribute.  In this case, the established identity SHOULD be applied to existing DTLS connections as well as new connections established using one of those fingerprints.  Note that I-D.ietf-rtcweb-jsep, Section 5.2.1 requires that each media section use the same set of fingerprints for every media section. </ins>  <ins> If the set of fingerprints changes, then the sender MUST either send a new 'identity' attribute or none at all.  Because a change in fingerprints also causes a new DTLS connection to be established, the receiver MUST discard all previously established identities. </ins> 6. 11.1. <ins> Rewrite the Identity section in more conventional offer/answer format. Clarify rules on changing identities. 11.2. </ins> Update discussion of IdP security model Replace "domain name" with RFC 3986 Authority Require support for ECDSA, PFS, and AEAD  <ins> 11.3. </ins> Update cipher suite profiles.
