XML Schemas

XML Schemas are a more precise way to model data with XML and are an update to the old XML DTDS. The final spec was approved in May by the W3C standards organization and is one of the hottest areas in XML programming. Just as the discovery of the Rosetta stone provided a way to establish the meaning of Egyptian hieroglyphics, XML schemas provide a way for organizations to establish the meaning of XML documents so they can be understood across different company systems. Each industry will have a set of shared vocabularies for describing data being exchanged across the Web, making schemas a cornerstone of e-commerce development.
