            Bug ID: 174248
           Summary: AX: Don't expose aria-roledescription value on
                    "generic" elements (e.g. div and span)
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Accessibility
          Assignee: webkit-unassigned at lists.webkit.org

The ARIA spec states: 

> User agents must not expose the aria-roledescription property if … The element to which aria-roledescription is applied does not have a valid WAI-ARIA role or does not have an implicit WAI-ARIA role semantic.

There is concern that this requirement is overly restrictive, but consensus that things like <div aria-rolescription="button"> do need to be prevented. So let's at least address that worst-case scenario.

See bug 163647 for more information.
