A wholistic RSS namespace for podcasting that is meant to synthesize the fragmented world of podcast namespaces. As elements are canonized, they will be added to this document so developers can begin implementation. The specifications below are considered locked and the team will prioritize backward compatibility. We are operating under the [Rules for Standards-Makers](http://scripting.com/2017/05/09/rulesForStandardsmakers.html).
- **language (optional):** The language of the linked transcript. If there is no language attribute given, the linked file is assumed to be the same language that is specified by the RSS `<language>` element.
- **rel (optional):** If the rel="captions" attribute is present, the linked file is considered to be a closed captions file, regardless of what the mime type is. In that scenario, time codes are assumed to be present in the file in some capacity.
This tag may be set to `yes` or `no`. The purpose is to tell other podcast platforms whether they are allowed to import this feed. A value of `yes` means that any attempt to import this feed into a new platform should be rejected. It is expected
that podcast hosting providers will enable a toggle in their GUI to allow their users to turn feed transfer lock on or off. When importing a feed, if the hosting provider has already verified the owner="" email address on their own system, and the
email matches what is listed in this tag, it is safe to import the feed.
- **owner:** The owner attribute is an email address that can be used to verify ownership of this feed during move and import operations. This could be a public email or a virtual email address at the hosting provider that redirects to the owner's true email address. This is a critical element, and it's expected that podcast hosting providers (if not providing virtual addresses) will allow setting this element's value in their GUI with an emphasis to their users of how important it is to have this be a valid, working email address.
