Moving Dominic's comments from that bug here:

Added a new bug:
https://bugs.webkit.org/show_bug.cgi?id=89103

isRole wouldn't work very well, we'd have to expose the enum to JavaScript. Instead we should just expose the WebCore role name as a string in JavaScript, and make it a compile error to add a new role without adding the role name.

I don't think we need to have role descriptions in cross-platform tests, that's a Mac-only concept. The WebCore role enum should encompass all distinct roles, and each platform should map a role to whatever makes sense on that platform - on Mac one role might map to a {role, roleDescription} tuple.
