- * {@link HTML_QuickForm2_Rule::setOptions() setOptions()} or to
- * {@link HTML_QuickForm2_Factory::registerRule()}. Regular expression
- * registered with the Factory overrides one set for the particular Rule
- * instance via setOptions().
- *
- * The Rule can also validate file uploads, in this case the regular expression
- * is applied to upload's 'name' field.
- *
- * The Rule considers empty fields (file upload fields with UPLOAD_ERR_NO_FILE)
- * as valid and doesn't try to test them with the regular expression.
