+=head1 DESCRIPTION
+    
+Unfortunately the Ikano API schema has xs:sequence everywhere, so we need to have most elements in a particular order.
+This class solves this problem by extending XML::Simple and overriding sorted_keys to provide the element order for each request.
+
+IMPORTANT: when using this class, XMLOut must have SuppressEmpty => 1 as an option.
+You will break everything otherwise.
