The Microsoft® Office XP Web Services Toolkit 2.0 brings the power of XML Web services to Office XP by enabling developers to use the Universal Description, Discovery, and Integration (UDDI) Business Registry or the URL to a Web Services Description Language (WSDL) file to reference XML Web services.
The Office XP Web Services Toolkit 2.0 supports SOAP 3.0 and complex data types. It was updated in March 2004 to support Windows 2000 SP4.
