cookiecrook has just created a new issue for https://github.com/w3c/webvtt: == Add a kind sub-type differentiator to new WebVTT ATTRIBUTES block == Add a kind sub-type differentiator to VTT ATTRIBUTES block (Depends on #511, prerequisite to #512) With #511, WebVTT will unambiguously have a way to clarify the `kind` of VTT (captions, descriptions, metadata, etc) in alignment with the HTML track element's `kind` attribute. However, there isn't yet a way to differentiate between subtypes of metadata, or subtypes of other kinds including descriptions. This (or another solution) seems necessary for parsing in order to solve the following use cases and more. Metadata kind sub-types: - time-coded video poster thumbnails ([common de facto use for preview scrubbing](https://github.com/w3c/webvtt/issues/511#issuecomment-1487497644) but no spec exists) - [WebVTT Issue 512: time-coded flash metadata](https://github.com/w3c/webvtt/issues/512) - [video chapter times, thumbnails, and titles](https://github.com/w3ctag/design-reviews/issues/952) Caption or Description sub-types: - text equivalent of audio description dialogue audio track ([VTT descriptions rendered on braille displays](https://www.w3.org/2022/09/14-audio-descriptions-minutes.html) used by blind and deafblind individuals) Since the ATTRIBUTES block is new for Issue #511 and PR #523, I decided to keep this complication out of the first PR with the goal of easing review. discussion, and progress.
