Hacks like this should not go here.  Place the hack in systemhtml.py instead.
Also, instead of hard coding the name DocumentFragment, I'd track a set of all
types like this as I expect we'll soon have multiple types to force adding
events for.  I know it will be a little bit more work to make the hack only
exist in systemhtml but that is better than bleeding our logic into
dartgenerator more than we have to.

I'm not sure how to put this in systemhtml.py, since all the logic for whether
or not to call AddEventAttributes is in dartgenerator.py.

[Jacob, 2012/03/06 22:41:59]

AddEventAttributes is really dart:html specific.  Go ahead and move all the
EventAttributes logic out of dartgenerator.py and stick it in the
HtmlSystemShared class or some other reasonable location in systemhtml.py

Done.
