A Declarative syntax to the 'addEventListener' DOM method is preferred for
the same reason that declarative animation is preferred over doing all your
animation with scripting. You are probably already aware of that, But you
don't really get to appreciate the difference until you write an authoring
tool or try to open and edit a file that was made with another authoring
tool.

You have to take the step sometime. And now seems like the perfect time,
since XHTML2 will probably support XML Events exclusively.

Okay, I'm a programmer, and I'm implementing this stuff. And I'm not the
kind of programmer that can be told: Do that, and then I just do it. I need
to be motivated. And implementing something that is just flawed doesn't
motivate me. That's why I want XML Events :)
