Answer 1

I just sharing with i think about it and Can edit and modify the answer so what i think the Purpose will be like if you want to hold the information about the View Objects and you don't want to add a new object in your xib for only to hold this information, you could just add your copyright notice into the File's Owner -> Document -> notes field. Also can be used for the Documentation purpose. And this information also will be included in the xml.

And As i also learn form this SO Questions It's saving an attributed string with a key of userComments to the storyboard file.
