The UDDI uses WSDL to describe interfaces to web services. In fact, in a business solution, it is very normal to search multiple UDDI registries or WSIL documents and then aggregate the returned result by using filtering and ranking techniques. SOAP was originally part of the specification that included the Web Services Description Language (WSDL) and Universal Description, Discovery, and Integration (UDDI). �-r�#)���-��s7e���{TXY���*;��n��E��-*�����a�-�`� )���i�.qSsT}�H�xj�� Universal Description, Discovery, and Integration (UDDI) is an XML-based registry for business internet services.

True. WSDL is a part of UDDI. Data types such as float, numbers, and strings are all simple data types, but there could be structured data types which may be provided by the web service. Because a Web Service may have multiple bindings (as defined in its WSDL description), a service may have multiple Green Pages, as each binding will need to be accessed differently.
