>From News.com: ------------------------ XML schemas, first introduced in May, are a new way of letting computers interpret languages and applications based on Extensible Markup Language (XML). XML is a technology that Web and application developers can use to craft their own markup languages with special tags and functions. Schemas tell a computer reading an XML document how to interpret tags that are not universally recognized. Schemas are meant to replace an existing technology called the Document Type Definition (DTD). Schemas are supposed to be a step up from DTDs because they are written in XML and support the use of XML namespaces, which let computers distinguish between similarly named tags from distinct XML-based languages that find their way into the same application. http://www.w3.org/TR/xmlschema-1/ http://www.w3.org/TR/xmlschema-2/ ------------------------ Jeff -- +----------------------------------+ | J.W.
