What the standard says
Headings and labels describe topic or purpose.
Why it matters
People skim by heading. "Overview" three times on one page is three dead ends.
What a failure looks like
- failsGeneric headings: "More", "Information", "Details".
- failsTwo different fields both labelled "Name".
How to fix it
- doSay what the section is about. Specific beats short.
How A11ySignal checks it
manual
No automated rule can judge this criterion, and we will not pretend otherwise. A clean scan does not mean 2.4.6 passes — it means nothing we can measure fails. This one needs a person.
What a tool cannot tell you
A tool sees that a heading exists, not whether it is descriptive.
