What Is WSDL 1.1 SOAP Extension?

This section describes the SOAP extension added in 2006 to the original 2001 WSDL 1.1 specification to support SOAP 1.2 binding. 7 language components introduced in WSDL 1.1 binding extension for SOAP 1.2.

What is WSDL 1.1 SOAP Extension? WSDL SOAP Extension adds extra language components to the WSDL 1.1 Framework to support SOAP binding.

In the original WSDL 1.1 language specification, "Web Services Description Language (WSDL) 1.1" (http://www.w3.org/TR/wsdl), published in 2001, SOAP Extension was designed to support SOAP 1.1 binding.

Later in 2006, a separate specification, "WSDL 1.1 Binding Extension for SOAP 1.2" (http://schemas.xmlsoap.org/wsdl/soap12/WSDL11SOAP12.pdf), was published to support SOAP 1.2 binding.

So technically speaking, we have two SOAP extensions: WSDL 1.1 binding extension for SOAP 1.1 and WSDL 1.1 binding extension for SOAP 1.2.

The WSDL 1.1 binding extension for SOAP 1.1 has been discussed earlier in this book. Now let's look at the WSDL 1.1 binding extension for SOAP 1.2.

Namespace URI for WSDL 1.1 binding extension for SOAP 1.2:

  xmlns:soap12="http://schemas.xmlsoap.org/wsdl/soap12/"

There are 6 language components introduced in WSDL 1.1 binding extension for SOAP 1.2. These language components can be used inside WSDL 1.1 framework components as shown below:

<wsdl:definitions ...>
  <wsdl:binding ...>
    <soap12:binding .../>
    <wsdl:operation ...>
      <soap12:operation .../>
      <wsdl:input>
        <soap12:body ...>
        <soap12:header .../>
          <soap12:headerfault .../>
        </soap12:header>
      </wsdl:input>
      <wsdl:output>
        <soap12:body .../>
        <soap12:header .../>
          <soap12:headerfault .../>
        </soap12:header>
      </wsdl:output>
      <wsdl:fault>
        <soap12:fault .../>
      </wsdl:fault>
    </wsdl:operation>
  </wsdl:binding>
  <wsdl:port ...>
      <soap12:address .../> 
  </wsdl:port>
</wsdl:definitions>
