ZF-8052: SoapClient is unable to handle <xsd:import>
Create a new Zend_Soap_Client_* that can handle .
SoapClient seems to be unable to handle and is causing an endless loop.
Workaround: * download WSDL and XSD files * change schemaLocation-URLs to local files * initialize SoapClient with modified WSDL file
Works fine, but I don't know whether this is the best way to solve this problem.
