Bug 181796 – AX: Implement support for Graphics ARIA roles

• Component: Accessibility
• Status: RESOLVED FIXED

[Joanmarie Diggs]

There is a graphics-aria spec [1] which introduces three roles:
* graphics-symbol
* graphics-document
* graphics-object

The platform mappings can be found in the graphics-aam spec [2].

Related: At the time we implemented the mappings for SVG defined in the svg-aam [3], I'm pretty sure the svg-aam itself had the platform details; now it says things like "Default Platform WAI-ARIA Role Mappings: graphics-symbol role ..." We might wish to make a similar adjustment in our support, and we should double-check nothing else has changed in the expected mappings.

We're blocked until we get some answers from the SVG AAM folks. So I opened bug 181856 for that work.

You don’t think we need a separate role for this kind of document?

At the time I did the patch, no. But given your question, along with what was stated today in https://github.com/w3c/svg-aam/issues/1#issuecomment-359493725, it seems we may have a use case for a separate/dedicated role for graphics document as well as for graphics symbol. The patch in comment #5 does that.
