On OS X, radio groups have a special role that differs from that of other group boxes. In HTML, this is only applied by ARIA, though, not by the regular fieldset element. pcoming patch adds a new internal role and maps it to the same native roles like ROLE_GROUPING on Linux and Windows, but uses the specialized role on OS X. Also, it adds a mapping for the xul:radiogroup element since that is also special from regular xul:groupbox elements.
