-- WSDL中绑定元素<binding/>的一点不理解
有个问题不太明白。wsdl定义绑定时，定义了三种，分别是soap:binding，HTTP GET & POST Binding，MIME Binding
但是如何区别一个绑定是种一种呢，好像没有一个明显的属性或者元素来区分。你要结合多个元素来区分。比如下面是WSDL官方文档下面定义的三个Soap,http/post,mime绑定。
为什么不直接在<binding>元素里面添加一个属性，来表明这个绑定的类型呢？是不是我有什么知识没理解的，还是由于历史原因，搞成了现在这样？
<binding name="StockQuoteSoap" type="tns:StockQuotePortType">
<soap:binding style="document" transport="http://example.com/smtp"/>
<operation name="SubscribeToQuotes">
<input message="tns:SubscribeToQuotes">
<soap:body parts="body" use="literal"/>
<soap:header message="tns:SubscribeToQuotes" part="subscribeheader" use="literal"/>
</input>
</operation>
</binding> <binding name="b3" type="pt1">
<http:binding verb="POST"/>
<operation name="o1">
<http:operation location="o1"/>
<input>
<mime:content type="application/x-www-form-urlencoded"/>
</input>
<output>
<mime:content type="image/gif"/>
<mime:content type="image/jpeg"/>
</output>
</operation>
</binding>
<binding name="b1" type="tns:pt1">
<operation name="GetCompanyInfo">
<soap:operation soapAction="http://example.com/GetCompanyInfo"/>
<input>
<soap:body use="literal"/>
</input>
<output>
<mime:multipartRelated>
<mime:part>
<soap:body parts="body" use="literal"/>
</mime:part>
<mime:part>
<mime:content part="docs" type="text/html"/>
</mime:part>
<mime:part>
<mime:content part="logo" type="image/gif"/>
<mime:content part="logo" type="image/jpeg"/>
</mime:part>
</mime:multipartRelated>
</output>
</operation>
</binding>
