type是这样定义的：
TStudent=class{row}
    XZQHBM:string;
    DWBM:string;
    DWMC:integer;
    end;
很顺利地将其转换为下面的文本：
男^李华^14^6287555
男^张三^16^8273425

可是我在处理下面的这个xml文件时，不知道如何定义type了，文件是这样的：
<xml xmlns:s='uuid:BDC6E3F0-6DA3-11d1-A2A3-00AA00C14882'
xmlns:dt='uuid:C2F41010-65B3-11d1-A29F-00AA00C14882'
xmlns:rs='urn:schemas-microsoft-com:rowset'
xmlns:z='#RowsetSchema'>
<s:Schema id='RowsetSchema'>
<s:ElementType name='row' content='eltOnly'>
  <s:AttributeType name='XZQHBM' rs:number='1' rs:writeunknown='true'>
   <s:datatype dt:type='string' dt:maxLength='8' rs:maybenull='false'/>
  </s:AttributeType>
  <s:AttributeType name='DWBM' rs:number='2' rs:writeunknown='true'>
   <s:datatype dt:type='string' dt:maxLength='12' rs:maybenull='false'/>
  </s:AttributeType>
  <s:AttributeType name='DWMC' rs:number='3' rs:nullable='true' rs:writeunknown='true'>
   <s:datatype dt:type='string' dt:maxLength='60'/>
  </s:AttributeType>
  <s:extends type='rs:rowbase'/>
</s:ElementType>
</s:Schema>
<rs:data>
<z:row XZQHBM='13032300' DWBM='101002' DWMC='人大常委会'/>
<z:row XZQHBM='13032300' DWBM='161006' DWMC='人民法院'/>
        <z:row XZQHBM='13032300' DWBM='766002' DWMC='工商联'/>
</rs:data>
</xml>

请高手指点着两个xml文件本质上有什么区别，我该如何定义type呢？xml有版本一说吗？
为什么这两个文件架构区别这么大呢？
