public static Element::setAttributes(array &$element, array $map)
Sets HTML attributes based on element properties.
Parameters
array $element: The renderable element to process. Passed by reference.
array $map: An associative array whose keys are element property names and whose values are the HTML attribute names to set on the corresponding property; e.g., array('#propertyname' => 'attributename').
