Standard ECMA-348 Web Services Description Language (WSDL) is an XML schema for describing Web services and how they can be accessed by Web based CSTA applications. Everything that an application needs to communicate with a Web service is described in a WSDL document. This Standard specifies a WSDL for the XML messages defined in ECMA-323, XML Protocol for Computer Supported Telecommunications Applications (CSTA) Phase III. All CSTA features (e.g., services and events) specified in ECMA-269 and ECMA-323 are specified in this Standard. CSTA WSDL facilitates the creation and deployment of web based CSTA applications. For example, by using CSTA WSDL with many industry Web services development environments, a web services developer can access CSTA features provided by a CSTA implementation without knowing details of the network or underlying transport protocols. The WSDL specified in this Standard is defined with XML and XML Schema. One example transport illustrated in this Standard is SOAP over HTTP. This Standard builds upon the XML data types and message formats specified in ECMA-323. Although a WSDL document contains both abstract definitions (WSDL messages and port type elements) and concrete protocol specific definitions (WSDL bindings, ports, and service elements), this CSTA WSDL Standard specifies only the abstract definitions of a WSDL document. The concrete protocol specific definitions are implementation specific and are outside the scope of this Standard. This Standard specifies port types for a subset of the profiles specified in ECMA-269. In December 2005 Ecma approved ECMA TR/90, which proposes amendments and additions to ECMA-348 when the underlying WS-Addressing and WS-Eventing technology has stabilised.
