Hi Charles, Maybe it should be redirected to the members of the RSS Advisory Board, right? I think that I'm not a relevant contact to apply for such a media type. I will not be able to exchange and provide additional information. Also, if the content of etc/mime.types is based on the IANA one[1], then why it provides this 'application/x-rss+XML' entry? What for?
Many thanks, Patrice [1] https://www.iana.org/assignments/media-types/
