Shepherd writeup

(1) What type of RFC is being requested (BCP, Proposed Standard, Internet Standard, Informational, Experimental, or Historic)? Why is this the proper type of RFC? Is this type of RFC indicated in the title page header? 
This document will be a standard track RFC. This document defines new RTP payload formats for the TTML, an XML based timed text format for live and file based workflows from W3C
The type is indicated on the title page

(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:
TTML (Timed Text Markup Language is a media type for  describing timed text such as closed captions (also known as  subtitles) in television workflows or broadcasts as XML.  This document specifies how TTML should be mapped into an RTP stream in live workflows including, but not restricted to, those described in the television broadcast oriented EBU-TT Part 3 specification.  This document does not define a media type for TTML but makes use of the existing application/ttml+xml media type.

Working Group Summary:
The content of the document was discussed with the W3C Timed Text Working Group (TTWG), 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?
This draft was discussed by the W3C Timed Text Working Group (TTWG) on 2019-02-07 and the document was updated based on their comments.  There is no media type registration. 
Who is the Document Shepherd? Who is the Responsible Area Director? 
Roni Even is the Document Shepherd.
The responsible AD is Barry Leiba.

(3) Briefly describe the review of this document that was performed by the Document Shepherd. If this version of the document is not ready for publication, please explain why the document is being forwarded to the IESG. 
The document shepherd reviewed the document in previous and current versions and found it ready for publication.
(4) Does the document Shepherd have any concerns about the depth or breadth of the reviews that have been performed? 
The document was reviewed by the W3C TTWG and Nigel Megitt (Chair, W3C TTWG) confirmed that tey do not have any further comments.
(5) Do portions of the document need review from a particular or from broader perspective, e.g., security, operational complexity, AAA, DNS, DHCP, XML, or internationalization? If so, describe the review that took place. 
(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 the document, or has concerns whether there really is a need for it. In any event, if the WG has discussed those issues and has indicated that it still wishes to advance the document, detail those concerns here. 
(7) Has each author confirmed that any and all appropriate IPR disclosures required for full conformance with the provisions of BCP 78 and BCP 79 have already been filed. If not, explain why?
Yes. The authors confirmed.
(8) Has an IPR disclosure been filed that references this document? If so, summarize any WG discussion and conclusion regarding the IPR disclosures. 
(9) How solid is the WG consensus behind this document? Does it represent the strong concurrence of a few individuals, with others being silent, or does the WG as a whole understand and agree with it? 
This is an RTP payload and usually the review is done by the interested parties. We had good feedback from W3C TTWG and the WG chair reviewed the document both on content and structure.
(10) Has anyone threatened an appeal or otherwise indicated extreme discontent? If so, please summarise the areas of conflict in separate email messages to the Responsible Area Director. (It should be in a separate email because this questionnaire is publicly available.) 
(11) Identify any ID nits the Document Shepherd has found in this document. (See and the Internet-Drafts Checklist). Boilerplate checks are not enough; this check needs to be thorough. 
No issue
(12) Describe how the document meets any required formal review criteria, such as the MIB Doctor, media type, and URI type reviews. 
No Need
(13) Have all references within this document been identified as either normative or informative? 
(14) Are there normative references to documents that are not ready for advancement or are otherwise in an unclear state? If such normative references exist, what is the plan for their completion? 
(15) Are there downward normative references references (see RFC 3967)? If so, list these downward references to support the Area Director in the Last Call procedure. 
None, there are normative references to non IETF documents.
(16) Will publication of this document change the status of any existing RFCs? Are those RFCs listed on the title page header, listed in the abstract, and discussed in the introduction? If the RFCs are not listed in the Abstract and Introduction, explain why, and point to the part of the document where the relationship of this document to the other RFCs is discussed. If this information is not in the document, explain why the WG considers it unnecessary. 
(17) Describe the Document Shepherd's review of the IANA considerations section, especially with regard to its consistency with the body of the document. Confirm that all protocol extensions that the document makes are associated with the appropriate reservations in IANA registries. Confirm that any referenced IANA registries have been clearly identified. Confirm that newly created IANA registries include a detailed specification of the initial contents for the registry, that allocations procedures for future registrations are defined, and a reasonable name for the new registry has been suggested (see RFC 8126). 
No IANA action
(18) List any new IANA registries that require Expert Review for future allocations. Provide any public guidance that the IESG would find useful in selecting the IANA Experts for these new registries. 
(19) Describe reviews and automated checks performed by the Document Shepherd to validate sections of the document written in a formal language, such as XML code, BNF rules, MIB definitions, etc.
The document has XML code but they are examples of the payload which ant not of RTP itself
