Section 21.1.4 says:

Type of Attribute: session-level

It should say:

Type of Attribute: media-level


Section 15.3 clearly says that "ice-mismatch" is media-level:

'"ice-mismatch" is a media-level
attribute only, and when present in an answer, indicates that the
offer arrived with a default destination for a media component that
didn't have a corresponding candidate attribute.'

Section Section 6.1 also implies that "ice-mismatch" is media-level:

"In some cases, the answer may omit a=candidate attributes for the
media streams, and instead include an a=ice-mismatch attribute for
one or more of the media streams in the SDP."
