As accessibility becomes a prioritized feature of all documents, its pertinent to include it without sacrificing aesthetics, which is Adobe's strength. One idea for this is for the designer to create the InDesign document as they normally would on an initial layer, and upon a secondary "layer" the plain text for an e-reader could be supplied, mapped to the corresponding visual layer. This could be a less destructive method than physically altering text box widths to avoid soft returns/rags, or creating new text boxes for each text/paragraph style. It would also export ready to go without further alteration in Acrobat. The "accessible" layer could either be manually placed, OR, through the help of AI be pulled out automatically as the designer adds content. A good example of a similar concept would be audio scripts/summary as an alternative to captions for video content (non-destructive but allows for accessibility) A predecessor to this would be an InDesign Accessibility Checker, but would take it much further to allow the designer to maintain organic, visually pleasing creative while also being sure to comply with accessibility standards.
