The group agreed to adopt this approach in general, but Michael is still working out some of the details related to how this will affect formal comment tracking, so we’re still using the private W3C tracker in the meantime. https://www.w3.org/Bugs/Public/show_bug.cgi?id=23803 > Here are some things that I think ARIA 1.1. should be updated with: > > 1.

ACTION-1380: #presentation should mention aria-hidden vs presentation role on raster and vector images in relation to ACTION-1379 https://www.w3.org/WAI/PF/Group/track/actions/1380 ACTION-1381: TAC and #presentation should cover shadow-DOM descendants (e.g. <video controls> in some user agents) https://www.w3.org/WAI/PF/Group/track/actions/1381 > 3.

ACTION-1379: TAC should cover rendered descendants from external sources: svg, iframe, etc. (Compose text and get final review form ARIA subteam) https://www.w3.org/WAI/PF/Group/track/actions/1379 > 4. Clarification, for role=Presentation, of what ”implicit native role > semantics” covers and what it does *not* cover. Definition and examples. If I understand you correctly, that’s up for each host language to declare (e.g. img@alt in HTML), but I can put in some examples with the actions listed above. Thanks Leif, James
