In 3.3.9 Additional accessibility information of the User Experience Guide for Displaying Accessibility Metadata 2.0

Structure
For information on any structuring aids that facilitate use of a resource (e.g., annotations, ARIA).

Do we want to include Annotations and is there a clearer definition of annotations?

To include other forms of navigation not specifically referenced in the Navigation section of the display guidelines?

Adaptation
For information on provisions in the content that enable reading in alternative access modes (e.g., closed captions, ruby annotations, sign language, transcript).

For adaptions for Ruby - do we create a separate section that corresponds to the Internationalization Terms section 4.2.7 of the Schema.org Accessibility Properties for Discoverability Vocabulary ?
Do we include some of the other terms? EDItEUR has not yet added ONIX codes for these as we are waiting to know if they are needed and will be used?

Tactile
For information on content that is available in tactile form (e.g., tactile content, tactile graphic, tactile objects).

How much Tactile content is being seen in the supply chain ? EDItEUR has not yet added ONIX codes for these as we are waiting to know if they are needed and will be used? So what guidance do we want to include in the document?

Other
For information that does not fall into one of the preceding categories (e.g., timing control and color dependent).

How much extra advice do we include here? Should we try and have mention for all the values that could be found in Schema or ONIX and therefore may need to be displayed?
