Abstract
An extended Web services description language (WSDL) is provided to allow for the merging of call flow XML with the interface description. This is accomplished through additional WSDL bindings for operations that associate an operation with segments or message points within the call flow. In addition, the extension to WSDL defines a set of interactions that provide additional semantics for how the operation interacts with the call flow. These interactions capture the interaction points between the WSDL. The WSDL interfaces that are created may be used for outbound interactions (i.e. initiated through Web services from some event within the call flow) or for the usual inbound request response. An additional lifecycle listener interface is used to convey different binding points between an enhanced converged Web service processing engine and a converged application implementation of the WSDL.
