Hi Andrew, Josh, and all, A key point of contention is in the Adapting Text SC discussion is in regard to SC text and testability. So I have a question to the group: Must SCs be testable on the face of the SC? In other words, from only reading the SC text, must testability be evident to provide normative testability? If it can't be tested true/false from the SC text, will it or won't it meet the SC criteria requirements? Some seem to say yes: "you need to say by how much or it isnt testable...the criteria need to be in the (success) criteria. Understanding can only make it clearer — not define it further..." - Gregg C Vanderheiden, 24 Jan 2017. https://lists.w3.org/Archives/Public/w3c-wai-gl/2017JanMar/0420.html "if it can't be tested true/false from the SC text, it won't meet the SC criteria. You can flesh things out in the understanding doc, but the SC needs to be a true/false statement" - Alastair Campbell, 10 Feb 2017 https://lists.w3.org/Archives/Public/public-low-vision-a11y-tf/2017Feb/0034.html Some seem to say no: "...moving the testing metrics for these SC to supporting documents, and I support that. I believe it's in keeping with the intent, which is that the user be able to choose their own display formatting, and how that's tested is essentially details (assuming, as Gregg Vanderheiden says, we have figured out how it will be tested, so we're sure it is testable)..." - Greg Lowney, 18 April 2017 https://www.w3.org/2002/09/wbs/35422/AdaptingTextSurvey/results The WCAG 2.1 Success Criteria Wiki page says, "Success Criteria shall... Be testable through automated or manual processes." https://www.w3.org/WAI/GL/wiki/WCAG_2.1_Success_Criteria It doesn't go into specifics regarding this matter. If we can come to consensus on this point, it may help move the discussion forward. Thank you. Kindest Regards, Laura -- Laura L. Carlson
