Original: It has been observed that specifications of new Real-time Transport Protocol (RTP) payload formats often forget to specify registration of the format's media type in the IANA registry "RTP Payload Formats Media Types" [RTP-FORMATS] as recommended by [RFC8088]. Perhaps: Often times, authors defining new Real-time Transport Protocol (RTP) payload formats forget to specify registration of the format's media type in the "RTP Payload Format Media Types" registry [RTP-FORMATS] as recommended by [RFC8088]. --> MW: I would rather in this case change tempus and say “Many times” Some times, authors defining new Real-time Transport Protocol (RTP) payload formats forgot to specify registration of the format's media type in the "RTP Payload Format Media Types" registry [RTP-FORMATS] as recommended by [RFC8088]. 3) <!-- [rfced] Is it correct that this document does not define "other means"? If yes, perhaps the text should indicate this is out of scope, as I expected this document to update the Media Types registry in some way to account for this information. Original (prior sentence included for context): This registry is not used for any purpose other than to track which media types actually have RTP payload formats. That purpose could be addressed through other means. --> Yes, declaring it out of scope could be a potential. We expect this to be addressed as part of the update of the media type registration procedure work in MediaMan WG which is ongoing. 4) <!-- [rfced] We find this text a bit tough to follow. Please consider whether the suggested text is more clear. Original: The Media Types registry [MEDIA-TYPES] is the crucial registry to register any Media Type to establish the media type used to identify the format in various signalling usages, to avoid collisions, and to reference their specifications. Perhaps It is crucial to register media types in the "Media Types" registry [MEDIA-TYPES] to identify the format in various signalling usages, avoid collisions, and reference the defining specifications. --> MW: I think your proposal works fine if we replace “crucial” with “required” 5) <!-- [rfced] For readability, may we update this text to be a list? In addition, may we add that this document has been listed as a reference in the registry (see the second bullet)? Original: To resolve this situation, this document performs the following actions. First, it updates the registry to include known RTP payload formats at the time of writing. Then, it closes the IANA Registry for RTP Payload Formats Media Types for future registration. Beyond instructing IANA to close this registry, the instructions to authors in [RFC8088] are updated so that registration in the closed registry is no longer mentioned. Perhaps: To resolve this situation, this document: * updates the "RTP Payload Format Media Types" registry to include known RTP payload formats at the time of writing. * closes the "RTP Payload Format Media Types" registry to future registrations and lists this RFC as a reference. * removes from [RFC8088] the instruction to register RTP payload formats in the "RTP Payload Format Media Types" registry. --> MW: Yes, this do looks better. 6) <!-- [rfced] What does "without affecting its status as part of an informational RFC" mean? Also, the second sentence is incomplete. Please clarify. Original: This paragraph is changed without affecting its status as part of an informational RFC. Thus removing the need to register in the "RTP Payload Format media types". Perhaps: The following paragraph is updated as shown below, thus removing the need for media types to be registered in the "RTP Payload Format Media Types" registry. --> MW: The following paragraph is updated as shown below, thus removing the need for media types to be registered in the "RTP Payload Format Media Types" registry. Note that this update does not impact the updated text and the rest of RFC 8088 status as informational RFC. There was raised comments that was worried that due to RFC 9751 is standards track this changed text would be elevated also to standards track. Thus, I think we should retain some note, but I suggest a reformulation above. 7) <!-- [rfced] We have updated the notes slightly. If they are accepted, we will ask IANA to update the registry accordingly. Original: NEW: "This registry has been closed as it was considered redundant as all RTP Payload formats are part of the Media Types registry (https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.iana.org%2Fassignments%2Fmedia-types%2Fmedia-types.xhtml&data=05%7C02%7Cmagnus.westerlund%40ericsson.com%7C8ee01dc6487c4afb23ce08dd556262f7%7C92e84cebfbfd47abbe52080c6b87953f%7C0%7C0%7C638760605627414370%7CUnknown%7CTWFpbGZsb3d8eyJFbXB0eU1hcGkiOnRydWUsIlYiOiIwLjAuMDAwMCIsIlAiOiJXaW4zMiIsIkFOIjoiTWFpbCIsIldUIjoyfQ%3D%3D%7C0%7C%7C%7C&sdata=J08GQwCNjjpBlkw%2FKf%2FcLKMqR98QAbKQZy0veka%2FujU%3D&reserved=0<https://www.iana.org/assignments/media-types/media-types.xhtml>).
