Microsoft® SQL Server™ 2000 shipped more than a year ago with built-in support for storing and retrieving XML data. Knowing ongoing work would be required after the release of SQL Server 2000 in order to stay current with evolving W3C standards for XML, Microsoft began releasing fully-supported, XML feature packs to the Web in the months after the release of SQL Server 2000. Available as a free download, these XML feature packs—called SQLXML (XML for SQL Server)—extend the XML capabilities of SQL Server 2000.
SQLXML 3.0 introduces Web Services to SQL Server 2000. With SQLXML 3.0, Stored Procedures and XML Templates can be exposed as a Web Service via SOAP.
SQLXML 3.0 also updates SQLXML 2.0's support for Diffgrams, understanding new features added since Microsoft Visual Studio® .NET Beta 2. And supports released versions of the .NET Framework and SOAP Toolkit.
Additionally, the features introduced in SQLXML 1.0 and SQLXML 2.0 are included in the download of SQLXML 3.0.
SP1 includes bug fixes, security enhancements, and performance increases made since the release of SQLXML 3.0.
