This often leads to the creation of a "vague" task, under which a set of non-similar tasks are grouped. This can be accomplished with an XSL Transform policy. WSDL is an XML-based protocol for information exchange in decentralized and distributed environments. Generally, data cannot be easily cached in memory between page loads.

WSDL contain every detail of web services like what is communication protocol method name, data type used. Complexities associated with the usage of various WS-* specifications are two of the most common disadvantages of the SOAP messaging model. Con: Some vendor solutions are single-vendor approaches which conflict with the open standards-based vision of Web Services. Designed to leverage existing technologies 3. Clients wishing to access a Web service can read and interpret its WSDL file to learn about the location of the service and its available operations. WSDL 2 can describe RESTful web service as well. - The WBS can quickly be outdated: Although (ideally) the WBS dictates your project schedule, it (the WBS) can become quickly outdated. As per W3C, web service can be defined as, a software system designed to support interoperable machine-to-machine interaction over a network. 1.
