Similar to Data Type Definitions (DTDS), XML Schemas provide for specification of the structure of an XML document. This chapter looks at XML Schemas and how you can use them to validate XML documents.
XML Schemas are well- formed XML documents. This means that, unlike DTD documents, they can be created and manipulated with XML parsers, such as the .NET objects in the System.Xml namespace or the MSXML DOM. XML Schemas have many advantages over DTDs, including support for data types and namespaces. They are readable and provide tremendous flexibility for describing an XML document.
World Wide Web Consortium RecommendationXML Schemas are a World Wide Web Consortium (W3C) Recommendation, which means that they have passed all other stages of the W3C approval process. This also means that tool support is more widespread now that the working draft is not a moving target. |
