What is the correct way to generate a header and body in a wsdl file?

Friends, I'm building a file wsdl that carries a header and body , which I build them in the binding of the same, the problem is when I generate the input request where the header is not build with the attributes with which I am creating.

 <wsdl:message name="NameVersionInfoHeader">
        <wsdl:part name="VersionInfoHeader" element="tns:VersionInfoHeader" />
      </wsdl:message>

    <wsdl:binding name="ServiceSoapBinding" type="tns:ServiceSoap">
        <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
        <wsdl:operation name="CreateVersion">
          <soap:operation soapAction="http://comverse-in.com/prepaid/ccws/CreateVersion" style="document"/>
          <wsdl:input>
            <soap:body use="literal"/>
            <soap:header message="tns:NameVersionInfoHeader" part="VersionInfoHeader" use="literal" />
          </wsdl:input>
          <wsdl:output>
            <soap:body use="literal"/> 
            <soap:header message="tns:NameVersionInfoHeader" part="VersionInfoHeader" use="literal" />      
          </wsdl:output>
        </wsdl:operation>
      </wsdl:binding>

This is the way I build my wsdl . The header I need to create with this structure.

<soapenv:Header>
      <ccws:VersionInfoHeader>     
         <ccws:ProductVersion></ccws:ProductVersion>     
         <ccws:CustomerVersion></ccws:CustomerVersion>
      </ccws:VersionInfoHeader>
   </soapenv:Header>

Only generates the following

<soapenv:Header/>

Thankful if anyone can help me.
