Description: WSDL models endpoints in terms of portTypes, abstract definitions of what a web service can do. Each portType is defined as a set of operations involving the exchange of abstract messages. Bindings are concrete definitions of how a portType\'s operations are invoked using a particular format and transport protocol, e.g., SOAP and HTTP. This would be fine except that SOAP bindings are defined as having one of two styles: document or RPC. Document style implies that a service is a message-oriented endpoint. RPC style implies that a service is a function-oriented endpoint.
