Context: Child (Same Domain)
I am being viewed as a child, through a parent, on the same domain.
I should have access to my parent's objects and properties, and my parent should have access to mine.
Context: Child (Different Domain)
I am being viewed as a child, through a parent, but not on the same domain.
This means I should not have access to my parent's objects and properties, and my parent should not have access to mine.
