	ITransientDeferredInstance	The ITransientDeferredInstance interface extends IDeferredInstance and adds the ability for the user to reset the deferred instance factory to its initial state (usually this implies releasing any known references to the component, such as the setting the owning document property that refers to the instance to null).
	IUIComponent	The IUIComponent interface defines the basic set of APIs that you must implement to create a child of a Flex container or list.
	IUID	The IUID interface defines the interface for objects that must have Unique Identifiers (UIDs) to uniquely identify the object.
