RFC Editor Note
Old:
The above is the minimum that IANA will accept. Attributes that are
expected to see widespread use and interoperability SHOULD be
documented with a standards-track RFC that specifies the attribute
more precisely.
New:
The above is the minimum that IANA will accept. The Expert
Reviewer will determine if the proposed attributes are expected
to see widespread use and interoperability; in that case, a
the attributes MUST be specified in a standards-track RFC.
Section 10, figure 5:
OLD:
ssrc-group-attr = "ssrc-group:" semantics *(SP ssrc-id)
; The definition of "semantics" is in RFC 3388.
; (It is the type of grouping being done.)
attribute =/ ssrc-group-attr
NEW:
ssrc-group-attr = "ssrc-group:" semantics *(SP ssrc-id)
semantics = "FEC" / "FID" / token
; Matches RFC 3388 definition and
; IANA registration rules in this doc.
token = <as defined in RFC 4566>
attribute =/ ssrc-group-attr
