Re: Hoisting SOAP Binding Attributes

+1 for eliminating repetitions in the binding.

I would suggest a complement/alternative to your proposal with something 
like defining the "operation scope" of a soap:operation EII in the binding.
This way, a soap:operation EII would be applicable for more than one 
operation defined in the portType.
Maybe by adding a target AII where to say that a particular 
soap:operation EII is used (by default)/(for operation o1, o2 and o3).

examples:
1)
<soap:binding>
    <soap:operation target="soap:default">

      <input>
        <soap:body use="encoded"
            namespace="http://example.com/stockquote"
            encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
      </input>
      <output>
        <soap:body use="encoded"
            namespace="http://example.com/stockquote"
            encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
      </output>

    </soap:operation>
</soap:binding>

2)
<soap:binding>
    <soap:operation target="o1 o2 o3 ">

	<input>
        <soap:body use="encoded"
            namespace="http://example.com/stockquote"
            encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
      </input>
      <output>
        <soap:body use="encoded"
            namespace="http://example.com/stockquote"
            encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
      </output>

    </soap:operation>
</soap:binding>
