Says who? It's a problem today, and will be a problem tomorrow, because of the very nature of what it is trying to assess. The only way out of this seems to be to ignore the problem altogether and just test the mechanistic aspect ("if element has alt attribute, pass, otherwise fail", sprinkled with some AI heuristics?) and call it a day instead, with a soft "above and beyond, here's some protocols/guides for the stuff that's not covered directly here". Admittedly, I'd quite like to be able to just outsource the boring "normative pass/fail" to a machine in the end and concentrate on education/improvement once a client gets past that initial "we just want to tick a box that says WCAG compliant" (though without the threat of litigation I wonder how many clients we'd be left with at that point ;) ). [...] The idea of the protocols seems to simply separate out subjectivity, but fundamentally is it still there? If a site gets extra points for stating that they will follow a protocol, then somebody (auditor, judge, ...) still then needs to go and apply their subjective view on whether their extra point is deserved or not. If a final total score still depends on summing the unambiguous unit test scores and the extra points, subjectivity will still end up influencing the final score - and we'll still see auditors disagreeing on whether a particular extra point is deserved or not, unless only the pure *promise* of following a particular protocol counts, rather than its use/implementation. Or unless legally only the unambiguous unit test scores will count, at which point why would a client bother with the extra points (other than kudos)? > I do understand that this is somewhat shocking to many, but I personally > cannot see another path forward, and it is clear from the first round of > feedback that industry are very unhappy with the amount of additional > subjectivity in our current draft, so I assert we do need to come up > with something different. Well yes, the crux of the issue is of course the conundrum of "guidelines" (in the sense of recommendations/best practices, not absolute edicts - thinking for instance of Apple's Human Interface Guidelines which even Apple themselves sometimes knowingly break) having been bent, for better or worse, into unambiguous "rules"/laws - turning them from something that can form the basis for improvement/discussions, a framing tool, to something that can potential lead to fines and law suits, sadly. That's been the fundamental tension. (Along the lines of the old Bill Hicks sketch about the supreme court defining what "pornography" is...) To be clear, the effort to reframe/try to tackle this problem is admirable, so not a sleight on you John. Just me airing my perennial frustration on how we've been trying for years, and still are, and will be long after I retire, to fit a square peg into a round hole, due to the very nature of what it is we're trying to define.
