Léonie. -- Léonie Watson - Senior accessibility engineer @LeonieWatson @PacielloGroup -----Original Message----- From: janina@rednote.net [mailto:janina@rednote.net] Sent: 29 May 2014 03:53 To: HTML Accessibility Task Force Subject: Call for Consensus (CfC); Alt Colleagues: This is a Call for Consensus (CfC) to the HTML-A11Y Task Force to confirm the sufficiency and accuracy of guidance on the alternative text attribute for images as provided by the following two related HTML-WG documents. It is also a Call for Consensus regarding proposed next steps for each of these documents. You will recall the relationship between these documents is that the first was initially created to help remedy perceived deficiencies in the second. In other words, initially guidance in these two documents was different, and the two did not agree. It is believed that over the past few years these differences have been successfully resolved. This CfC tests this thesis. For the record we are requesting the Task Force confirm this consensus, or point out specific remaining insufficiencies. 1.) HTML5: Techniques for providing useful text alternatives http://rawgit.com/w3c/alt-techniques/master/index.html This document was initially created to help remedy deficiencies regarding the alt attribute in early drafts of the HTML 5.0 specification. Over the past few years, guidance originally present in this document has been migrated to the HTML specification itself and removed from this document. However, it is believed that this document should nevertheless be published because the remaining content will continue to provide valuable guidance to authors. Recent edits to this document can be seen in the W3C Bugzilla bugs shown at the following URI: http://tinyurl.com/kjvj3bb A permanent, though very long URI for these bugs is: https://www.w3.org/Bugs/Public/buglist.cgi?bug_status=UNCONFIRMED&bug_status =NEW&bug_status=ASSIGNED&bug_status=REOPENED&bug_status=RESOLVED&bug_status= VERIFIED&bug_status=CLOSED&component=CR%20alt%20techniques%20%28editor%3A%20 Steven%20Faulkner%29&list_id=37965&product=HTML%20WG&query_format=advanced QUESTION 1: Does the Task Force a.) Accept the changes identified above to this document; and b.) Recommend that work on this document be terminated; and c.) Support publication of this document by the HTML-WG as a W3C Note. 2.) HTML 5.0 Sec. 4.7.1.1 Requirements for providing text to act as an alternative for images http://www.w3.org/html/wg/drafts/html/master/embedded-content.html#alt As noted above there have been significant edits to this section of the HTML 5.0 specification in order that this specification might best reflect current consensus best practice guidance regarding alt. These changes are documented by the following W3C Bugzilla bugs: 8827* <https://www.w3.org/Bugs/Public/show_bug.cgi?id=8827> Inappropriate spec text and advice where images are not known 9215* <https://www.w3.org/Bugs/Public/show_bug.cgi?id=9215> Provide a Webcam example that is in accord with WCAG 2 or Defer to "HTML5: Techniques for providing useful text alternatives" 9216* <https://www.w3.org/Bugs/Public/show_bug.cgi?id=9216> Provide a CAPTCHA example that is in accord with WCAG 2 or Defer to "HTML5: Techniques for providing useful text alternatives" 10708* <https://www.w3.org/Bugs/Public/show_bug.cgi?id=10708> change normative alt text authoring requirements to informative advice 13428* <https://www.w3.org/Bugs/Public/show_bug.cgi?id=13428> Remove Requirements for providing text to act as an alternative for images 20401* <https://www.w3.org/Bugs/Public/show_bug.cgi?id=20401> non conforming use of title attribute in example code 20402* <https://www.w3.org/Bugs/Public/show_bug.cgi?id=20402> use of title attribute in example is incorrect 20403* <https://www.w3.org/Bugs/Public/show_bug.cgi?id=20403> spec states plural conditions when only 1 condition is conforming 20404* <https://www.w3.org/Bugs/Public/show_bug.cgi?id=20404> more non conforming uses of title attribute in example code 20405* <https://www.w3.org/Bugs/Public/show_bug.cgi?id=20405> plural 'conditions' used when only one condition exists 21420* <https://www.w3.org/Bugs/Public/show_bug.cgi?id=21420> note about conforming image is incorrect 21941* <https://www.w3.org/Bugs/Public/show_bug.cgi?id=21941> Spaghetti Monster reference is provocative 22161* <https://www.w3.org/Bugs/Public/show_bug.cgi?id=22161> paragraph contains inaccuracies 22373* <https://www.w3.org/Bugs/Public/show_bug.cgi?id=22373> Should a a logo example that is not linked. 22375* <https://www.w3.org/Bugs/Public/show_bug.cgi?id=22375> Images of text where there is also an image 22438* <https://www.w3.org/Bugs/Public/show_bug.cgi?id=22438> Alt text for an image to a home page of a web site 22773* <https://www.w3.org/Bugs/Public/show_bug.cgi?id=22773> Captions in image alt attributes 22774* <https://www.w3.org/Bugs/Public/show_bug.cgi?id=22774> 4.8.1.1.3 Image alts and explanations 22791* <https://www.w3.org/Bugs/Public/show_bug.cgi?id=22791> Alt text for charts, graphs etc should (when sensible) state what the graphic is 23059* <https://www.w3.org/Bugs/Public/show_bug.cgi?id=23059> Alt text section should address a headshot of a person with their name written 23207* <https://www.w3.org/Bugs/Public/show_bug.cgi?id=23207> Alt text should identify image class when relevant 23397* <https://www.w3.org/Bugs/Public/show_bug.cgi?id=23397> Expand advice regarding the use of images for gaiji, novel currency symbols, and the like 24001* <https://www.w3.org/Bugs/Public/show_bug.cgi?id=24001> alt text example in wrong place 25264* <https://www.w3.org/Bugs/Public/show_bug.cgi?id=25264> - Pointer to additional resources in section on text alternatives for images QUESTION 2: Does the Task Force: a.)
