Thank you, Jamie. I'm taking that screen readers may need to a context element, when error message pops up, as a use case for a reverse relation (if not, please correct me).
Could you also comment my guess about aria-details? If a screen reader skips aria-details elements when navigating, then what mechanism we'd use for aria-details element detection.
