| * 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. | |
