Why would an XML document have a targetnamespace attribute set?

[Julien Martin]

Hello,

I have an xml document, namely a WSDL file and I am trying to understand why the "definitions" element have "targetNamespace" attribute set??? I thought this attribute was only for schemas. Is this not confusing? Is this legal? Why wsdl files don't have a schema to validate themselves from?

Here is my document:

<?xml version="1.0" encoding="UTF-8"?>
<definitions name="EJBWebServiceOne" targetNamespace="urn:EJBWebServiceOne/wsdl" xmlns="http://schemas.xmlsoap.org/wsdl/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="urn:EJBWebServiceOne/wsdl" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <types>
  </types>
  <message name="EJBWebServiceOneSEI_myOperationResponse">
    <part name="result" type="xsd:string"/>
  </message>
  <message name="EJBWebServiceOneSEI_myOperation">
    <part name="String_1" type="xsd:string"/>
  </message>
  <portType name="EJBWebServiceOneSEI">
    <operation name="myOperation" parameterOrder="String_1">
      <input message="tns:EJBWebServiceOneSEI_myOperation"/>
      <output message="tns:EJBWebServiceOneSEI_myOperationResponse"/>
    </operation>
  </portType>
  <binding name="EJBWebServiceOneSEIBinding" type="tns:EJBWebServiceOneSEI">
    <soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http"/>
    <operation name="myOperation">
      <soap :-o	 peration soapAction=""/>
      <input>
        <soap:body namespace="urn:EJBWebServiceOne/wsdl" use="literal"/>
      </input>
      <output>
        <soap:body namespace="urn:EJBWebServiceOne/wsdl" use="literal"/>
      </output>
    </operation>
  </binding>
  <service name="EJBWebServiceOne">
    <port binding="tns:EJBWebServiceOneSEIBinding" name="EJBWebServiceOneSEIPort">
      <soap:address location="http://ordinateur:8080/EJBModuleWS/EJBWebServiceOne"/>
    </port>
  </service>
</definitions>
