Here is an
example of a WSDL document:
This WSDL document contains
six main elements:
The definitions element must
be the root element of a WSDL document. It defines the name of the
web service and declares multiple namespaces used in the
document.
The types element provides
data type definitions that are used to describe the messages
exchanged.
The message element describes
a one-way message. This can be a request or response message. It
defines the name of the message and contains zero or more message
part elements. These elements represent the parameters of the
message.
The portType element combines
multiple message elements into a complete operation. Each operation
refers to an input message and output message.
The binding element describes
how the service is implemented on the wire. It specifies concrete
protocol and data format specifications for the operations and
messages defined by a particular portType.
The service element describes
the address for invoking the specified service. Since USoft web
services are soap services, this URL starts with soap:address.
