Sailesh, You make a valid point in your post. I think there should be greater consensus on whether H69 is sufficient or not for SC 2.4.1, which seemed to be the intent of the original post by Vivienne - correct me otherwise. Also note that the definition of section (from understanding SC 2.4.10 – Key Terms) reads: “A self-contained portion of written content that deals with one or more related topics or thoughts. Note: A section may consist of one or more paragraphs and include graphics, tables, lists and sub-sections.” Correct me, but this definition seems to imply that a section is part of the written content besides other things. If one is to replace ‘headings’ with ‘structure’ and ‘content’ with ‘sections,’ H42 becomes, “…HTML and XHTML heading markup to provide semantic code for headings (implying *structure*) in the content (implying *from which Sections are derived*). Isn’t this H69 written differently? On a related note, G141 and H69 may talk about the same thing but then refer to different success criteria. Shouldn’t there be a single technique on headings which points to multiple success criteria? To help understand, I took a line from each of the techniques below: **H42: The objective of this technique is to use HTML and XHTML heading markup to provide semantic code for headings in the content. (SC 1.3.1) **H69: The objective of this technique is to use section headings to convey the structure of the content. (SC 2.4.1) **G141: The objective of this technique is to ensure that sections have headings that identify them. (SC 1.3.1; 2.4.10) -Devarshi >>Sailesh wrote: H69 is authored with reference to SC 2.4.1 and not SC 2.4.10. That's why I maintain that being able to skip to an h1 or h2 that hopefully is the main content is a byproduct of user agent's feature that lets one skip headings to comprehend page structure etc. Then it does not deserve to be a separate technique but maybe merged with H42. Yes as you note, some pages do not have headings at start of some content sections. Typically left nav or breadcrumb nav and sometimes even main content, though there might be other headings on the page. One may insert invisible headings to aid screen reader navigation ... this is exploiting the screen reader's heading navigation feature. This will not work for sighted keyboard users. Adding visible headings where none exist will help the page comply with SC 2.4.10 (AAA) and might provide an alternative way to skip to main content SC 2.4.1).
