(2) The IESG approval announcement includes a Document Announcement Write-Up.
Please provide such a Document Announcement Write-Up. Recent examples can be
found in the "Action" announcements for approved documents. The approval
announcement contains the following sections: Technical Summary: This document
updates RFC 5761 by clarifying the SDP offer/answer   negotiation of RTP and

the attribute.

was particularly rough? The document was discussed in the meetings,  and on the
mailing list. The open issues were addressed and there are no open issues,
there was consensus on the content of the document.

Document Quality:
Are there existing implementations of the protocol? Have a significant number
of vendors indicated their plan to implement the specification? Are there any
reviewers that merit special mention as having done a thorough review, e.g.,
one that resulted in important changes or a conclusion that the document had no
substantive issues? If there was a MIB Doctor, Media Type or other expert
review, what was its course (briefly)? In the case of a Media Type review, on
what date was the request posted? The document clarifies some text in RFC5761
based also on implementation experience. Personnel: Who is the Document
Shepherd? Who is the Responsible Area Director? Roni Even is the Document
Shepherd. The responsible AD is Ben Campbell. (3) Briefly describe the review
of this document that was performed by the Document Shepherd. If this version

internationalization? If so, describe the review that took place. None.

(6) Describe any specific concerns or issues that the Document Shepherd has
with this document that the Responsible Area Director and/or the IESG should be
aware of? For example, perhaps he or she is uncomfortable with certain parts of
