I’ve now specified particular values for [[Class]] on host objects (regular ones and host exception objects). For host objects, it is the identifier of the “primary prototype interface” (which, if you put a [PrototypeRoot] extended attribute appropriately on Node and Event, is the name of the “main” interface). If there’s no primary prototype interface, no particular value is required. For exception host objects, it’s the identifier of the exception. I’ve left [[Class]] on interface objects and interface prototype objects undefined (which was discussed later on in the thread that starts with Anne’s mail above). -- Cameron McCormack ≝ http://mcc.id.au/
