614572 - MAP html:aside, footer and header scoped to the body element, main and nav to IA2 role landmark.

Status: RESOLVED FIXED

(Core :: Disability Access APIs, defect)

Description

[David Bolter [:davidb] (NeedInfo me for attention)]

This is contingent on IA2 1.2.1 point release introducing a new role that is distinct from IA2_ROLE_NOTE.

We still need to figure out how to normalize how we expose aria role=complementary and how we expose html:aside.

Yeah.

Note we currently map html:aside internally to ROLE_NOTE (and IA2_ROLE_NOTE).

I'm not clear on what should be done here. It looks like we follow the spec [1]

We already map the ARIA complementary role to IA2_ROLE_LANDMARK, as per https://www.w3.org/TR/core-aam-1.1/#role-map-complementary. However, html:aside is not mapped to the same role, even though the HTML Accessibility API mapping spec says so: https://www.w3.org/TR/html-aam-1.0/#html-element-role-mappings.

The same is true for navigation: https://www.w3.org/TR/core-aam-1.1/#role-map-navigation, or rather its corresponding nav element, header, footer (both scoped to the body element), and main.

Attachment: Bug 614572 - Expose the correct new landmark role for HTML aside, header, footer, main and nav elements, r=jamie

According to the HTML Accessibility API mappings spec, aside, footer, header, main and nav elements should be mapped to the WAI-ARIA landmark role exposure. For footer and header, this is only true if scoped to the body element.

This patch changes the exposed roles to the new landmark mapping for the various platforms, as we already do for the corresponding WAI-ARIA roles.
