As the Internet moves forward, Extensible Markup Language, XML, is poised to become the method for interchanging information among all sorts of devices. For instance, a hand-held Global Positioning System device might be Internet-enabled to receive weather reports encoded in XML. This hypothetical device doesn't have a lot of extra memory to do all the error-checking and "forgiving" that a browser can do with your HTML. This means that servers must ensure that the data is "good to go" before sending it to the device. XML Schema is a new method that the World Wide Web Consortium has come up with to help make sure your data is valid.
