/**
		 * <p>
		 * Adds a listener to the object referenced by <code>identifier</code>.
		 * This listener will be notified if a property of the item is to be
		 * changed. This identifier is specific to mechanism being used. In the
		 * case of the Eclipse workbench, this is the command identifier.
		 * </p>
		 * <p>
		 * A single instance of the listener may only ever be associated with
		 * one identifier. Attempts to add the listener twice (without a removal
		 * in between) has undefined behaviour.

		 * @param identifier
		 *            The identifier of the item to which the listener should be
		 *            attached; must not be <code>null</code>.
