Dealing with indistinct complex type definiton in existing WSDL

I have been attempting to create a SOAP client to consume services generated by an established server. When making use of any function which retrieves information as anything except single values, I encounter an error: *"SOAP-ERROR: Encoding: object hasn't 'schema' property"* Obtaining the function and type information from an existing SOAP server via:

    $client = new SoapClient($wsdlUrl, $opts);
     $reply = $client->__getFunctions();
    var_dump($reply);
    print "\n\n";
    $reply = $client->__getTypes();
    var_dump($reply);
    print "\n\n";

Generates:

... [2]=> string(59) "GetCountriesResponse GetCountries(GetCountries $parameters)" ... [4]=> string(47) "struct GetCountries { ds ds; string status; }" [5]=> string(46) "struct ds { <anyXML> schema; <anyXML> any; }" [6]=> string(55) "struct GetCountriesResponse { ds ds; string status; }" [7]=> string(46) "struct ds { <anyXML> schema; <anyXML> any; }" ... From what I can learn of the implementation of the server, this "ds" structure is very similar to ADOdb's /*ADORecordSet */structure, or more exactly the fields hash array of the record set.

The question is: How does one make use of the *SoapVar *call to construct an appropriate schema / type definition to keep the SOAP extension happy? Deepest thanks, JT McDuffie
