// This demonstrates how I get around a really nasty problem: If the 
// SOAP client won't send a parameter when the value is NULL, the 
// SoapServer will fail with "Missing parameter" when giving the WSDL 
// in the first parameter of the SoapServer constructor. If you give 
// NULL as first parameter to the SoapServer constructor, your method 
// will be called with a wrong parameter order.
// 
// With the PhpWsdlProxy class I try to get around the problem, but 
// complex type return values must be returned with PHPs SoapVar 
// object then. Primitive return types like string, int or boolean don't 
// need a special handling.
// To get rid of the NULL problem you need to ensure that the PHP 
// SoapServer has no knowledge of the WSDL. To ensure this, set the 
// PhpWsdl::$UseProxyWsdl property to FALSE (is FALSE per default).
//
// If you want to mix class and global methods, you need to use the proxy.
