Bug 107650 – HTML5 promotes DL from specific 'definition list' to superset 'description list'; accessibility strings and accessors should be updated to match.

• Component: Accessibility
• Status: RESOLVED FIXED

[James Craig]

HTML5 promotes DL from specific 'definition list' to superset 'description list' which includes, but is not not limited to, definitions. Accessibility strings and accessors should be updated to match. e.g. accessors (e.g. AXDefinitionListDefinitionText) should reference description lists, and role description strings should change from 'definition' to 'description'

string and accessors mods, and new layout test.

Patch includes string and accessor changes, as well as a layout test that verifies role/subrole/roleDescription on many HTML elements and all of the ARIA 1.0 roles.

if ARIA still has a definition role, then maybe we should continue having a DefiniteListRole, and add a new DescriptionListRole

it seems unlikely that you need to update this file

is this part of another patch?

subrole only really exists on Mac, so this should probably be a mac test only

can you use a format like 

H1
    Role: AXHeading
    AXSubrole: 
    AXRoleDescription: heading

or something that shows which is which

Done. Added new "DefinitionRole" for the ARIA role, b/c it's not related to lists.

It contained one of the accessors and an was an easy update, but okay. Reverted.

this layout test should be in a separate patch. it doesn't really relate to this specific change

I specifically added the test case for the DL/DD/DT elements and the 'definition' role it contains. Adding the rest of the roles and elements was a trivial amount of effort for a worthwhile gain.

Same as previous, but without new layout test, which I'll add as a separate patch.

Chromium side looks good, thanks. No Chromium API changes, just making it compile, so it's fine to commit.
