SVG event handlers, how to pass the event object?

[ATC]

When calling an event handler such as onmouse or onmouseover, how do I pass the event object containing the mouse coordinates etc?

[ATC]

The reserved name 'evt' contains the mouse event. Example:
onclick="call_handler(evt);"

In the corresponding javascript, use:
function callhandler(event) {
  object = event.target; // object now contains the element
}
