 	@discussion	A MIDIUMPMutableEndpoint must be cache enabled before it is visible via API.
 				Note that Function Blocks may only be registered to uncached MIDIUMPMutableEndpoint
 				objects.
+
+				Disabling an endpoint also stops delivery to its destinationCallback. Re-enabling the 
+				endpoint resumes delivery to the same callback.
+
+				If this method returns NO, the endpoint is left as it was found, including whether
+				delivery to destinationCallback is running.
+ 
+				Note: Because both enabling and disabling synchronize against delivery, this method must
+				not be called from within the endpoint's own destinationCallback.
