function _jquery_ui_filter_dialog_prepare_replacer($matches) {
  $attributes = _jquery_ui_filter_parse_tag_attributes($matches[0]);

  // Look for json in rel attribute.
  if (empty($attributes['rel'])) {

  }

  // Parse the JSON insures that no one can inject JavaScript into the site.
  $json = json_decode(str_replace("'", '"', $attributes['rel']));

  // Since filter_xss() removes {} (ie Netscape 4 JS entities) we are going to
  // escape (urlencode) the json string.
  // - Once HTML 5 is support we can use the data attribute.
