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 .... !
