∟"types" - The Container Element for Data Types

This section describes 'types', the container element that has extensibility elements from other language to define data types used to describe messages for Web service operations.

"types" is a top level element of a WSDL 1.1 document. "types" is used as a container to include elements from another language to define data types used to describe messages for Web service operations. The syntax of "types" is very simple:

<wsdl:types>
  ... extensibility elements from other language...
</wsdl:types>

Here is an example of "types" element:

  <wsdl:types>
    <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
      targetNamespace="https://www.herongyang.com/Service/">
      <xsd:element name="HelloRequest" type="xsd:string"/>
      <xsd:element name="HelloResponse" type="xsd:string"/>
    </xsd:schema>
  </wsdl:types>

In this example,

The XML Schema language is used to provide extensibility elements.
targetNamespace="https://www.herongyang.com/Service/" is needed to make data types available in the target namespace of the WSDL document.
Two data types, HelloRequest and HelloResponse, are defined.
