/**
 * This header file lists up all event messages.
 * Before including this header file, you should define:
 * NS_EVENT_MESSAGE(aMessage)
 *
 * Additionally, you can specify following macro for e*First and e*Last.
 * NS_EVENT_MESSAGE_FIRST_LAST(aMessage, aFirst, aLast)
 * This is optional, if you need only actual event messages, you don't need
 * to define this macro.
 *
 * Naming rules of the event messages:
 * 0. Starting with "e" prefix and use camelcase.
 * 1. Basically, use same name as the DOM name which is fired at dispatching
 *    the event.
 * 2. If the event message name becomes too generic, e.g., "eInvalid", that may
 *    conflict with another enum's item name, append something after the "e"
 *    prefix, e.g., "eFormInvalid".
