| * Rule checking that uploaded file size does not exceed the given limit | |

| * The Rule needs one configuration parameter for its work: the size limit. | |
| * This limit 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 one. | |
| * | |
| * Note that if file upload failed due to upload_max_filesize php.ini setting | |
| * or MAX_FILE_SIZE form field, then this rule won't even be called, due to | |
| * File element's built-in validation setting the error message. | |
| * | |
| * The Rule considers missing file uploads (UPLOAD_ERR_NO_FILE) valid. | |
