 /**
  * Elgg checkbox input
  * Displays a checkbox input field
+ * NB: This also includes a hidden input with the same name as the checkboxes
+ * to make sure something is sent to the server.  The default value is 0.
+ * If using JS, be specific to avoid selecting the hidden default value:
+ * 	$('input[type=checkbox][name=internalname])
  *
  * @package Elgg
  * @subpackage Core

- * @uses $vars['value'] The current value, if any
- * @uses $vars['js'] Any Javascript to enter into the input tag
- * @uses $vars['internalname'] The name of the input field
- * @uses $vars['options'] An array of strings representing the label => options for the checkbox field
+ * @uses string $vars['internalname'] The name of the input fields (Forced to an array by appending [])
+ * @uses array $vars['options'] An array of strings representing the label => option for the each checkbox field
+ * @uses string $vars['internalid'] The id for each input field. Optional (Only use this with a single value.)
+ * @uses string $vars['default'] The default value to send if nothing is checked. Optional, defaults to 0.
