+ * Rule checking that the field is not empty

+ * Handles simple form fields, file uploads and Containers.
+ *
+ * When validating <select multiple> fields and Containers it may use an
+ * optional configuration parameter for minimum number of nonempty values,
+ * defaulting to 1. It can be passed either to
+ * {@link HTML_QuickForm2_Rule::__construct() the Rule constructor} as local
+ * configuration or to {@link HTML_QuickForm2_Factory::registerRule()} as
+ * global one. As usual, global configuration overrides local.

+ * // Required rule is 'nonempty' with a bit of special handling
+ * $login->addRule('required', 'Please provide your login');
+ * $multiSelect->addRule('required', 'Please select at least two options', 2);
