 * Defines the interface for entity browser displays.

 * user. They wrap around and encapsulate the entity browser. Examples include:
 *
 * - Displaying the entity browser on its own standalone page.
 * - Displaying the entity browser in an iframe.
 * - Displaying the entity browser in a modal dialog box.

   *   is needed as the widget may display after a new bootstrap, which would
   *   discard the current form state. Arbitrary values can be added and used
   *   by widgets, if needed.

   *        an array of options to pass to the plugin's validate method.
