Add 'alt' text for iframes to conform to accessibility requirements

It looks as though this particular rule could be addressed by including text in the iframe. As a test, I made the following modification:

/**
 * Theme function for 'default' vimeo field formatter.
 */
function theme_vimeo_formatter_default($element) {
  if (isset($element['#item']['value']) && !empty($element['#item']['value']) ) {
    $video_vid = $element['#item']['value'];
    return '<iframe src="http://player.vimeo.com/video/' . $video_vid . '?title=0&amp;byline=0&amp;portrait=0" 
    width="' . variable_get('vimeo_width', 640) . '" height="' . variable_get('vimeo_height', 360) . '" frameborder="0">Your browser does not support iframes.</iframe>';
  }
  else {
    // Nothing to output
    return '';
  }
}

i.e., adding "Your browser does not support iframes" inside the iframe, and the page now passes the Cynthia Says section 508 scan (see http://cynthiasays.com/).

An ideal solution would be to make this text configurable in some way, but even a generic replacement should satisfy automated section 508 screeners.

(Now if we could just get them to support closed-captioning...)

Changing (belatedly) to a feature request. This seems like a simple fix, and would serve as a bandaid for anyone trying to use Vimeo on a site where Section 508 compliance is required.

Note: I can't speak to whether this would satisfy WCAG.
