An announcement from TIBCO Software Inc. describes the release of a new streaming XML validator with full support for W3C XML Schema. Details: Tibco has "announced the commercial release of XML Validate, a member of the TIBCO Extensibility product family. XML Validate is an enterprise-grade solution for validating streaming XML documents or messages against an XML Schema or DTD. The Simple API for XML (SAX)-based implementation for run-time validation provides organizations with the core component in developing high bandwidth, XML-based processing. This release of XML Validate is also the first commercially available validator to fully support the World Wide Web Consortium (W3C) XML Schema Recommendation. The XML Schema Recommendation was released [2001-05-02] by the W3C... this XML Schema validation support will facilitate the creation of XML driven ecosystems based on open-standards. Additionally, XML Validate supports the validation of DTDs to allow connectivity with organizations not currently using XML Schema. XML Validate is a core building block for creating an e-commerce processing engine for XML documents and messages. As organizations conduct e-commerce with a growing and global audience, the processing capabilities of XML Validate can scale to the demand. XML Validate has the potential of handling millions of transactions per day per server. XML Validate can easily be inserted into an existing XML parsing scenario, enabling validation to occur the instant it is received by the parser. Because SAX is an event-based API, XML Validate is the ideal solution in a streaming run-time environment, creating an enterprise-grade XML processing engine."
