Hi David, I didn’t express it very well on the call, but I think my core objection to the failure technique is that it changes (in practice) the results of testing a page. Question: In the period between WCAG 2.0 being released and ARIA landmarks becoming well known / used (to any degree), did you fail pages that did not use a heading or text to identify regions of the page like headers, footers etc? I know I didn’t. I promoted the use of headings (hidden if necessary) to identify navigation and other page furniture, and emphasised that a document should make sense when read without styling (which has a similar effect). However, pre-landmarks I did not have the concept of page-regions in the same way as I do now. We were missing the concept and standardised terms for regions of the page, not just the implementation. Therefore I didn’t fail pages that did not identify regions of the page. So in my mind adding a failure for this is an effective change to what the SC had meant in practice. On adding dates: Sure, an approved date seems like a good idea, presumably the technique (or even failure ;-) shouldn’t substantively change once it has been approved then?
