I am not familiar with the concept of attaching an event to an element;
I do not understand what you or the text are trying to convey. The words
you use to express whatever you are trying to express are meaningless to
me. They do not make sense. This is not rocket science, if you have code
like
document.addEventListener('SVGMousewheel', callback, false);
then you are attaching a listener to something that is not the Document
node's documentElement. This is clearly outside of the "may only" clause
above, yet there does not seem anything bad about this code. And if you
have this code, and the SVGMousewheel event bubbles (which it does per
13.2), DOM Level 3 Events requires implementations to pass control to
the `callback` when the event occurs. Implementations "MUST NOT" do that
according to the text above. That, too, does not make sense.
