The expectation for aria-owns is that a developer can use it to group controls that are not otherwise grouped in DOM. Spec for of aria-owns: http://www.w3.org/TR/wai-aria-1.1/#aria-owns Here is a test case: <div role="radiogroup" aria-owns="r1 r2 r3"> <div role="radio" id="r1">Alpha</div> <div role="radio" id="r1">Beta</div> </div> <!-- this one, too. --> <div role="radio" id="r3">Gamma</div> In this case the 3rd radio button "Gamma" should be included in the radio group. However, when VoiceOver looks at this it only sees two radio buttons in the group, the 3rd is announced as a radio button without a group.
