Hi John, You wrote [1]: > I note that Laura just posted the related bits and bobs that currently > surround this issue in HTML5. For many of us, "don't use CAPTCHAs - > the end" is the answer rather than trying to repair a broken tool that > fails on its basic premise on many levels; This probably gets back to WAI CG's recommendation that: * that HTML5 state that "For guidance on accessibility requirements for text alternatives authors should consult WCAG 2.0." * and that HTML should not provide any guidance that conflicts with WCAG. http://www.w3.org/2009/06/Text-Alternatives-in-HTML5 In this thread so far am hearing several CAPTCHA solutions for the HTML 5 spec: 1. Keep CAPTCHA out of HTML5. Say nothing about it in the spec. Remove the example [2]. 1. Delete the CAPTCHA example in the HTML spec and state: "Don't use CAPTCHAs". This seems to conflict with WCAG as it already has CAPTCHA technique documents [3] [4]. Would it be feasible to ask to have the WCAG techniques documents changed to say "Don't use CAPTCHAs"? 2. Delete the CAPTCHA example in the HTML spec and refer and authors to WCAG 2.0 for guidance. 3. Delete the CAPTCHA example in the HTML spec and refer authors to Steve's document [5] where he is willing to expand on the inaccessibility of CAPTCHA and provide advice on how to make it accessible as possible if it is used [6]. 4. Delete the CAPTCHA example in the HTML spec and refer authors to WCAG 2.0 and Steve's doc . 5. Improve the CAPTCHA example in the HTML spec so that it is in line with WCAG 2.0 and its technique documents as well as Steve's document. Any other solutions on the table?
