However, by "script" I meant to include Java as well. There would be  
no reason for Java to user this interface on the global object  
either, and a Java "script" would not be allowed to use the interface  
per the spec. The intent of the interface is for Java event handlers  
to implement it, so that the implementation can call the handler and  
tell it to register itself. It just doesn't make sense that the  
global object would implement it too.

I don't get why the global object is required to implement an  
interface that application code may never call. This seems like a  
long-ago error in the specification, I do not understand why the SVG  
WG wishes to retain the error, regardless of how much practical  
effect it may have.

Just to be super clear on this:

- The global object implementing EventListenerInitializer2 is *not*  
required for Java event handlers to work. In fact, it plays  
absolutely no part in registering Java event handlers.

- Neither Java handler/script code nor ECMAScript handler/script code  
may call the one method in this interface on any object.

So you end up with a method that only the implementation would be  
allowed to call, but it doesn't want or need to ever. Is it the  
position of the SVG WG that despite this SVGGlobal should still  
inherit from EventListenerInitializer2?
