It is clear, but it is clearly in direct conflict with the new UA reqs in #aria-describedat. >> The WAI-ARIA specification neither requires or forbids user agents from >> enhancing native presentation and interaction behaviors on the basis of >> WAI-ARIA markup. [1] And then later, a direct contradiction in #aria-describedat: >> User agents SHOULD provide a device-independent mechanism to allow a >> user to navigate the user agent to content referenced by the aria- >> describedat attribute. User agents SHOULD also provide a device- >> independent mechanism to return the user's focus from the descriptive >> content view to the original content view. [2] These are RFC-2119 *requirements* for the user agent to enhance its native presentation and interaction behaviors on the basis of WAI-ARIA markup.
