Support the new markup in the ARIA annotations editor’s draft (3 new roles, 1 new property): suggestion, mark, comment, aria-description This feature enables new semantics: - Comments - Text highlights with semantic meaning, just like <mark> - Suggestions for changes, e.g. by another author in a Google Doc - Additional related information to be semantically tied to an element, allowing descriptions, definitions, footnotes and comments to be tied to another element.


To support screen reader accessibility of comments, suggestions and other annotations in published documents and online word processing scenarios such as Google Docs, iCloud Pages, and MS Office Online. This is not currently possible without resorting to live region hacks, which are not as reliable as semantics and do not work well with Braille displays. As a result, screen reader users have non-optimal support for collaboration features of online word processors.
