Re: FXL Accessibility (was Re: [Minutes] EPUB WG, 2nd vF2F day minutes 2021-10-29)

What would be great is a common initiative, targeting a "single source" model that appears impossible today due to the absence of proper "FXL + accessible" authoring tools. 

We should maybe restart the discussion (+ make it a specification) on what is required in EPUB FXL content documents to make them reflowable and accessible, e.g. by a simple XSLT? 
- blocks must be entered in the XHTML document in their reading order 
- headings must be correct
- images must be described, captions must be attached to the images
- ruby must be real ruby, not floating labels

what else? (no real need for page breaks, as one document = one page)

I think it’s simply a matter of “chicken and egg” – does the work of this group to define the best practices/standards for a11y in FXL proceed the creation or should we (Adobe) try to take the lead by exporting some things that we think will/do work?!?

In addition to all the issues raised in the meeting, let me also add one that most of you don’t think about…user additions to content!  Think annotations & bookmarks!  They need to work on both the FXL and reflowable versions of the content, in reasonable and understandable ways.  Today Web Annots are targeted to a specific HTML document, which means that w/o some work (and going beyond the spec), they wouldn’t show on the alternate.  Even if it did work, would it be as meaningful if the content isn’t in the “same place”?   It’s a problem for both the annotation creator as well as the annotation presentation system.
