I amended Zend_Soap_Wsdl_Strategy_ArrayOfTypeComplex::addComplexType().
Changing the (sic) ...
throw new Zend_Soap_Wsdl_Exception("Infinite recursion, cannot nest
'".$type."' into itsself.");
to ...
return "tns:$type";
and all is working just fine.
Obviously, I may be breaking something here, but I've not come across
it yet. Early days .... !
