Note: The WML specification states that calls to library functions that are not supported by the browser should return invalid. Because of this, all the above functions should be tested against their return value, and proper action should be taken in case a function returns invalid.
注意：WML的规范是：如果请求的库函数（Library Function）不能被浏览器支持，那将返回“无效”（invalid）；由于这点原因，上述的函数必须通过它们的返回值进行测试；而当函数返回“无效（invalid）”时也能够做出适当的反应。
