You can't use usual delegation (from mootools-more). However since it's
SVG/VML, I think the events bubble like normal DOM. So if you subscribe
(addEvent equivalent) an event to an element, which contains other elements,
the parent elements will fire the event as well. So you could inspect the
event object (probably the first argument) to see if there's something
useful.
myElement.subscribe('click', function(event){
console.dir(event);
});
Probably you can't check for event.target.tagName or use
Slick.match(event.target, 'a.class'); because the tagnames might be
different between SVG and VML. You should probably experiment a bit because
I'm not sure about it either yet ;)
