2.1.1 [DOM Level 2 - Events] Section 1.2.1, Basic event flow

V0001:

The specification states:

 Each event has an EventTarget toward which the event is directed by the DOM 
 implementation.

Quirks Mode, IE7 Mode, and IE8 Mode (All Versions)

Each event has a srcElement property, rather than an EventTarget, that represents the object that fired the event.

V0002:

The specification states:

 It is expected that actions taken by EventListeners may cause additional events to 
 fire. Additional events should be handled in a synchronous manner and may cause 
 reentrancy into the event model.

Quirks Mode, IE7 Mode, and IE8 Mode (All Versions)

Additional events are handled asynchronously and do not cause reentrancy into the event model.
