Structure
Each WSDL 1.1 document can be divided into the following logical parts:
- definition of data types (types) - determining the type of XML messages sent and received by the service
- data elements (message) - messages used by the web service
- abstract operations (portType) - a list of operations that can be performed with messages
- service binding (binding) - the way the message will be delivered
WSDL Example
<message name = "getTermRequest" >
<part name = "term" type = "xs: string" />
</message>
<message name = "getTermResponse" >
<part name = "value" type = "xs: string" />
</message>
<portType name = "glossaryTerms" >
<operation name = "getTerm" >
<input message = "getTermRequest" />
<output message = "getTermResponse" />
</operation>
</portType>
