 * Default theme implementation for status messages.
 *
 * Displays status, error, and warning messages, grouped by type.
 *
 * An invisible heading identifies the messages for assistive technology.
 * Sighted users see a colored box. See http://www.w3.org/TR/WCAG-TECHS/H69.html
 * for info.
 *
 * Add an ARIA label to the contentinfo area so that assistive technology
 * user agents will better describe this landmark.
 *
 * Available variables:
 * - message_list: List of messages to be displayed, grouped by type.
 * - status_headings: List of all status types.
 * - display: (optional) May have a value of 'status' or 'error' when only
 *   displaying messages of that specific type.
 * - attributes: HTML attributes for the element, including:
 *   - class: HTML classes.
 *
 * @see template_preprocess_status_messages()
