Whats new in WSDL 2.0 on XML.com

WSDL 1.2 was renamed WSDL 2.0 because of its substantial differences from WSDL 1.1.

Some of these changes include:

• Adding further semantics to the description language. This is one of the reasons for making targetNamespace a required attribute of the definitions element in WSDL 2.0.
• Removal of message constructs. These are specified using the XML schema type system in the types element.
• No support for operator overloading.
• PortTypes renamed to interfaces. Support for interface inheritance is achieved by using the extends attribute in the interface element.
• Ports renamed to endpoints.
