Hi Alestair I did not fail sites on 1.3.1 on not making Headers, footers, navigation, and main content programatically determinable before the advent of Landmark s and HTML and I still don't although I point out that they should do this. and give that an issue number as an important practice, with minimal investment and high returns. So clients do it, some clients say, "just give me the failures" WCAG is supposed to be ever green and technologically independent to give it a longer life. That's why we decided to make the very difficult decision to remove any mention of technology in the SCs. If we can't keep up with the most basic important accessibility feature such are regions, then we've failed at that goal... There are very few sites existing today on the web that we'd be asked to evaluate that were made before Landmarks were in mainstream use around 2010. (6 years ago). Anyway, my proposal was kind of a test. The "ever green" strategy of WCAG 2 failed for failures (and worked for techniques). So we need to address this in 2.1, and I'm glad that the feedback about provide a date field in techniques has been positive. It's a small thing, but might help solve the problem moving forward. I'm really hoping we don't adopt the squishy policy of not providing failures in WCAG Next. I think WCAG would have been a failure without the common failures.... they are used by tools, by authors, by banks some of which told me that's all they look at :( ... They are critical to the clarity required about common ways authors mess up. Failures are a bright line in the sand. They are not squishy like the success criteria can be, full of exceptions that require expert interpretation, where one can argue about whether 1.3.1 Info and Relations really means blind people should not have information about the relationship between a footer, nav, and the main body. I'm willing to table the failure to WCAG NEXT, with the confidence that we won't drop the ball on failures.
