如何在wsdl文件中找到服务合同？

Question

我有一个wsdl文件要分析。在那里，我得找到service contracts。

wsdl文件的一部分：

 <wsdl:types>

 <s:schema elementFormDefault="qualified" targetNamespace="http://tempuri.org/">
 <s:element name="SubmitApplication">
  <s:complexType>
   <s:sequence>
     <s:element minOccurs="0" maxOccurs="1" name="doc" type="tns:DocApplication" />
     <s:element minOccurs="1" maxOccurs="1" name="submittedDate" type="s:dateTime" />
     <s:element minOccurs="1" maxOccurs="1" name="category" type="s:unsignedByte" />
   </s:sequence>
  </s:complexType>
 </s:element>

  <s:complexType name="DocApplication">
   <s:sequence>
     <s:element minOccurs="1" maxOccurs="1" name="docId" type="s:int" />
     <s:element minOccurs="0" maxOccurs="1" name="title" type="s:string" />
     <s:element minOccurs="0" maxOccurs="1" name="author" type="s:string" />
     <s:element minOccurs="0" maxOccurs="1" name="description" type="s:string" />
     <s:element minOccurs="1" maxOccurs="1" name="datechanged" type="s:dateTime" />
    </s:sequence>
  </s:complexType>

 <s:element name="SubmitApplicationResponse">
  <s:complexType>
   <s:sequence>
     <s:element minOccurs="1" maxOccurs="1" name="SubmitApplicationResult" type="s:boolean" />
   </s:sequence>
  </s:complexType> 

我已经发现其中一个服务合同可以是

DocApplication (int docId, string title, string author, string description, date datechanged) ;

在这里，如何从int文件中找到返回类型（void / wsdl / etc）？
