Problem with RPC/encoded WSDL

Question

I'm having trouble calling a web service that is based on an RPC-encoded WSDL. I've already made slight changes to the WSDL, so that I get a work-able message type for mapping purposes. These changes are based on <a href="http://www.ws-i.org/Profiles/BasicProfile-1.0-2004-04-16.html#refinement16556272"><b>soapenc:Array</b> recommendations in WSDL 1.1 Section 2.2</a> for declaration of array types.
Here's a snippet of the WSDL:
<wsdl:definitions ...> 
  <wsdl:types>   
    <schema ...>
      <complexType name="ArrayOf_tns1_ServiceOption">
        <complexContent>
          <restriction base="soapenc:Array">
            <attribute ref="soapenc:arrayType"
              wsdl:arrayType="tns1:ServiceOption[]"
              xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"/>
          </restriction>
        </complexContent>
      </complexType>
    </schema>
    <schema ...>
      <complexType name="ServiceOption">
        <sequence>
          <element name="key" nillable="true"
                    type="xsd:string"/>
          <element name="value" nillable="true"
                    type="xsd:string"/>
        </sequence>
      </complexType>
    </schema>
  </wsdl:types>
</wsdl:definitions>
I've changed it to:
<wsdl:definitions ...> 
  <wsdl:types>   
    <schema ...>
      <complexType name="ArrayOf_tns1_ServiceOption">
        <sequence>
          <element name="ServiceOption"
                    type="tns1:ServiceOption"
                    minOccurs="0" maxOccurs="unbounded"/>
        </sequence>
      </complexType>
    </schema>
    </schema>
    <schema ...>
      <complexType name="ServiceOption">
        <sequence>
          <element name="key" nillable="true"
                    type="xsd:string"/>
          <element name="value" nillable="true"
                    type="xsd:string"/>
        </sequence>
      </complexType>
    </schema>
  </wsdl:types>
</wsdl:definitions>
The above changes have allowed me to make message mappings. But the I still get an error when sending a request to the web service. It seems that it requires the <b>xsi:type</b> and <b>soapenc:arrayType</b> attributes for arrays.
<b>How can I create these attributes? How does XI handle RPC-encoded WSDLs?</b> I haven't encountered these problems with document-literal WSDLs.
Thanks in advance.

Hi Lorenzo,
the extended support of rpc-style does <b>not</b> include the support of soapenc:array. It just addresses the root of the message and its direct children (as discussed in the thread where I added this hint).
In the documentation of External Definitions you can find a hint where to find a list of supported XSD/DTD/WSDL-features. However, also there you will find no hint on the fact that soapenc:array is not supported. The reason for this is, that soapenc:array is specified in none of these standards. It is some artifact that SOAP smuggled into XSD. For good reasons WS-I prohibits the use of this artifact.
Hence, if you need support for argumentation I can only point out the WS-I document I already linked.
