Hi!

This comes from OOP.

Protected - when you create subclass of that class, subclass will be able to work with protected item, but other objects will not be able to access it.

Hidden - Only class can access it. Either subclass or other objects cannot accedd this item. This is useful for hidden implementation if internal class logic.

Well, all above concerned to a single class only. When you have container and make hidden/protected property in it, contained objects will not be able to access that hidden/protected property from the code. Protected/hidden do not aply across the containership.
