Hi all, In an effort to progress the recent issue discussed on the thread 'Heading techniques', I'm starting a new thread here. I want to close the previous thread *unless* there is some substantive new information that the group can use to help us progress. In order to help us frame the issues and identify some useful actions, the chairs have discussed the issue and some (if not all) issues and potential actions are outlined below. Heading Thread ISSUES: ISSUE 1: Lack of accessibility support in using headers to meet 2.4.1, from keyboard only users who are not screen reader users. Potential action/comment: This is currently largely a user agent issue. ISSUE 2: If there was no visible heading before the main content for instance following the repetitive banner/nav block, then heading navigation simply cannot be relied upon for passing SC 2.4.1 and H69 will not apply. Potential action/comment: This has to be looked at on a case by case basis - there may be other markup patterns applied and WCAG does not want to be overly proscriptive. ISSUE: According to the document Sailesh shared http://mars.dequecloud.com/demo/Aria-heading.htm SC 2.4.10 (AAA) clarifies that, "heading" is used in its general sense and includes titles and other ways to add a heading to different types of content. WCAG2 does not define the term "heading" or "section heading". We may need to make a clearer distinction with in these techniques about what constitutes a heading in the first place? Potential action/comment: This is something that the working group can review. We may need to provide a better definition. #ISSUES: Can ARIA role="heading" be used as a part of h69? Potential action/comment: [Josh notes] <chair hat off> Seems like overkill – if not needed. But there may be a case where there is a preceeding heading over some section of content that could benefit from having it’s content marked up a such (using role=heading). <chair hat on> If someone wants to author a technique and bring it to the group - then please do. #ISSUE: One comment was that H69 goes beyond requirements of SC 2.4.1 and SC 2.4.10. Potential action/comment: H69 may be due a rewrite and we encourage working group members to improve or enhance existing techniques. #ISSUE: no WCAG requirement for AT to be able to navigate by headings or display a list of headings on a page. Potential action/comment:[Josh notes: <chair hat off>] I don’t think this is correct as IMO WCAG doesn’t need to have this as a requirement. The ability to be able to navigate content etc by the use of AT is a byproduct of their presence within the web page or application. We could possibly call this out better as a teachable moment within our supporting docs but IMO there is no need it make it any kind of requirement. <chair hat on> Some final take away thoughts. One of the overriding issues here, seems to me, to be with the current wording/purpose of H69. Currently headings are mentioned as the main way of providing information about the structure of web page content, but this may not be the only way for a user to get a sense of what the document structure is. It was one of the main ways when this technique was actually written but now there are other ways of doing this via ARIA or indeed other new semantics within HTML5 such as <article> <section> elements and so on. The current version of H69 states: The objective of this technique is to use section headings to convey the structure of the content. Heading markup can be used: • to indicate start of main content • to mark up section headings within the main content area • to demarcate different navigational sections like top or main navigation, left or secondary navigation and footer navigation to mark up images of text that are used as headings The first goal can be achieved using <main> or role=main. Leaving the second and third items aside, the third item can be addressed via <section> elements or suitable ARIA roles. Obviously they were not around at the time this technique was written but are now valid patterns. I therefore urge interested working group members to help update and shape this technique so it supports new design patterns and markup methods, and then present that to the group. #ISSUE: Can we update h69 to include 2.4.10? #We suggested that working group members come up with an alternative technique that address 2.4.10 in a minimal way for WG review. We hope this helps to provide a more cohesive overview and some next steps. Thanks -- Joshue O Connor/Andrew Kirkpatrick WCAG working group co-chairs
