For HTML elements, then it is the HTMLwg which defines which ARIA attributes are permitted globally or non-globally: http://www.w3.org/TR/html5/content-models#wai-aria Did you mean to ask for justification for why it should be permitted on other elements than those of role='img'? Without HTML5's restrictions, then all ARIA attributes are, in princple, 'global', since ARIA is intended for use in any host language - html, xhtml, svg, mathml etc. But the HTMLwg has, for instance, not declared @aria-label as invalid on <img>, despite the fact that <img> already has @alt. -- Leif H Silli
