<message> web service 使用的消息
<types> web service 使用的数据类型
<binding> web service 使用的通信协议
一个 WSDL 文档的主要结构是类似这样的：
<definitions>
<types>
definition of types........
</types>
<message>
definition of a message....
</message>
<portType>
definition of a port.......
</portType>
<binding>
definition of a binding....
