Bug 235065 – AX: HTML AAM Update to aside mapping

• Component: Accessibility
• Status: RESOLVED FIXED

[Scott]

HTML AAM issue https://github.com/w3c/html-aam/pull/350 revises the mapping of the aside element.

When an aside is scoped to the body element, or main element - allowing generic or presentational elements as ancestors - the aside element would map to the complementary landmark.

some examples:

body
  div
    aside = complementary

or

body 
  main
   aside = complementary

or

body 
  div
    main
      section role=presentation
        aside = complementary


Otherwise, if not scoped to the body or the main element, the aside element would map to the generic role.

body
  main
    section
      aside = generic

here is a test case https://scottaohara.github.io/testing/aside/

[Scott]

Note: test case has been updated to include instances of where aside would need to map to role=complementary because it has been given an accessible name.  This is not a new change per the update to HTML AAM, but I had forgotten to provide an example in the test case.

Did this change make it into a WPT computedrole test?

I think this needs an update to the following test:
