Support tables

Assertions are conditions that must be met for the feature to be considered as "supported". Only "MUST" assertions need to be met for minimal "support". "SHOULD" and "MAY" assertions indicates support that goes above and beyond. Note that there is not an explicit standard that dictates these assertions, and as such, they are likely opinionated. Minimal support reflects that the structure, relationships, and functionality of the feature are conveyed and operable by assistive technology rather than minimal conformance to any specific WCAG SC. As such, a feature might not meet all "MUST" assertions but still be usable (potentially frustratingly so).

li element: The screen reader MUST convey the position of the current list item in the set

Rationale: A screen reader user needs to know their position in a list.

Examples of assistive technologies support this assertion:

  • When in an ordered list context, the role might be conveyed with the position of the list item (1, 2, 3, etc.).
  • When in an unordered list context, the role might be conveyed by the word "bullet" or information about the position of the item in the list.
  • The position of the first item in the list might be implied by the first announcement of list semantics.

This assertion is from the li element feature.
