When parsing the WSDL at:

I get the repeated error log:

   *   Procedure: ::WS::Utils::parseScheme Client domNode0A270EFC 2 serviceInfo tnsCount
   *   Error: Unknown type reference xs:schema in type Cip_list

with the call stack:
<verbatim>
Unknown forward type reference {xs:schema} in {Cip_list}
    while executing
"parseElementalType $mode results $serviceName $element $tns"
    (procedure "parseElementalType" line 95)
    invoked from within
"parseElementalType $mode serviceInfo $serviceName $element $tns"
</verbatim>

and the error stack:
<verbatim>
INNER:invokeStk1 parseElementalType Client results 2 domNode0A2C0314 tns1
CALL:parseElementalType Client serviceInfo 2 domNode0A2C0264 tns1
CALL:::WS::Utils::parseScheme Client domNode0A270EFC 2 serviceInfo tnsCount
</verbatim>

The wsdl snippet of Cip_list is:

<verbatim>
  <wsdl:types>
    <s:schema elementFormDefault="qualified"
      ...
      <s:element name="STS_2_2_CIOsp_PDC_CIP_B1Response">
        <s:complexType>
          <s:sequence>
            <s:element minOccurs="1" maxOccurs="1" name="STS_2_2_CIOsp_PDC_CIP_B1Result" type="s:int" />
            <s:element minOccurs="0" maxOccurs="1" name="Cip_list">
              <s:complexType>
                <s:sequence>
                  <s:element ref="s:schema" />
                  <s:any />
                </s:sequence>
              </s:complexType>
            </s:element>
            <s:element minOccurs="0" maxOccurs="1" name="Errors" type="s:string" />
          </s:sequence>
        </s:complexType>
      </s:element>
      ...
</verbatim>

So, there is a reference to the whole schema. This means probably that any type may be used or whatever.
Has anybody a clue what that means and how to implement it ?

Thank you in advance,
