Add support for soap:Array types with complex content:

<complexType name="Foo">
    <all>
        <element name="id" type="string" />
    </all>
</complexType>
<complexType name="ArrayOfFoo" xmlns:soap-enc="http://schemas.xmlsoap.org/soap/encoding/">
    <complexContent>
        <restriction base="soap-enc:Array">
            <attribute ref="soap-enc:arrayType" wsdl:arrayType="tns:Foo[]"/>
        </restriction>
    </complexContent>
</complexType>
<element name="testType" minOccurs="1" maxOccurs="1" type="tns:ArrayOfFoo" />

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
  xmlns:tns="http://test-uri/"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:xsd="http://www.w3.org/2001/XMLSchema"
  xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/">
  <SOAP-ENV:Body SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
      <tns:test>
          <testParam SOAP-ENC:arrayType="tns:Foo[2]" xsi:type="tns:ArrayOfFoo">
              <item xsi:type="tns:Foo">
                <id xsi:type="xsd:string">abc</id>
              </item>
              <item xsi:type="tns:Foo">
                <id xsi:type="xsd:string">def</id>
              </item>
          </testParam>
      </tns:test>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>
