< It is now probably down to the judgment of any specific case to determine if the use of H80 alone can count as sufficient to meet SC 2.4.4 Link Purpose. Yes -- I should made my "(when accessibility supported)" emphasis a little stronger -- that is with specific assistive technology and user agents -- but as you point out that is a very limited set of technology not available on mobile, etc. -- so this likely could only be relied upon an internal environment. Whether the link text is sufficient or not to describe the topic or purpose is up for debate -- the heading information may not be necessary to understand the link in certain situations -- but certainly this is a judgement call that people will have to make. It would be helpful to provide a decision tree. For example, this tree would underscore what other factors play into this such as links with the same name, etc. Jonathan Jonathan Avila Chief Accessibility Officer SSB BART Group jon.avila@ssbbartgroup.com 703.637.8957 (Office) Visit us online: Website | Twitter | Facebook | Linkedin | Blog Check out our Digital Accessibility Webinars! -----Original Message----- From: Detlev Fischer [mailto:detlev.fischer@testkreis.de] Sent: Monday, May 02, 2016 10:00 AM To: w3c-wai-gl@w3.org; w3c-wai-ig@w3.org; Jonathan Avila Subject: Re: Not hearing grouping labels for checkboxes, radio buttons and link lists. Just note that H80 is no longer listed as Sufficient Technique, just as Advisory. For those scratching their heads, "Understanding Techniques" ( https://www.w3.org/TR/2014/NOTE-UNDERSTANDING-WCAG20-20140916/understanding-techniques.html ) says about Advisory Techniques "they may not be sufficient to meet the full requirements of the success criteria" which implies that they may well be, given the right circumstances. It is now probably down to the judgment of any specific case to determine if the use of H80 alone can count as sufficient to meet SC 2.4.4 Link Purpose. Or put differently, the use of H80 cannot automatically considered insufficient for meeting the SC - at least that is my interpretation of the fog of disclaimers that has grown around the Techniques in the last couple of years.

It was an information and relationship that was visual but not perceivable to blind people except by exploring around and guessing. Soon after, Landmarks came out and solved the problem.
