It'll go into the Pseudo-Elements spec when someone picks that up again.

For now, just put a note into the ARIA stuff that it's expected that
CSS will define a way to explicitly provide alternative text for
generated content. Feel free to sketch it in the note if you'd like.

How universal is @data-fallback? If it is exclusive to HTML5, then this belongs in the HTML5 section of the TAC (i.e. not the core section).

Move to Implementation guide. This has bigger impact on test tools and wcag authoring practices.

This requires coodination with the CSS Accessibility Task Force as it requires work by CSS and Host languages as well and is thus for not implemented in any browser today.
