SOAP Binding Extension

This section describes the SOAP Binding Extension added to the WSDL 2.0 Core language to enable Web services applications to use SOAP (Simple Object Access Protocol).

What Is SOAP Binding? SOAP Binding is an extension to the WSDL 2.0 Core Language to enable Web services applications to use SOAP (Simple Object Access Protocol). SOAP Binding is SOAP version independent, applying to both SOAP 1.1 and SOAP 1.2.

When HTTP is used as the underlying protocol, a subset of HTTP Binding is used together with SOAP Binding.

SOAP Binding provides additional attributes and sub elements to the "binding" element in a WSDL document as shown below:

<description xmlns:wsoap= "http://www.w3.org/ns/wsdl/soap" ...>
  ...
  <binding name="token" interface="qname"
    type="http://www.w3.org/ns/wsdl/soap"
    wsoap:version="string"
    wsoap:protocol="uri"
    wsoap:mepDefault="uri">

    <wsoap:module .../>
    
    <fault ref="qname"
      wsoap:code="qname/token"
      wsoap:subcodes="qname/token">
      <wsoap:module ... />
      <wsoap:header ... />
    </fault>

    <operation ref="qname" 
      wsoap:mep="uri"
      wsoap:action="uri">

      <wsoap:module ... />

      <input ...>
        <wsoap:module ... />
        <wsoap:header ... />
      </input>

      <output ...>
        <wsoap:module ... />
        <wsoap:header ... />
      </output>

      <infault ...>
        <wsoap:module ... />
      </infault>

      <outfault ...>
        <wsoap:module ... />
      </outfault>

    </operation>

  </binding>
