The delegate can verify the final state of the text storage object; it can’t change the text storage object’s characters without leaving it in an inconsistent state, but if necessary it can change attributes. Note that even in this case it’s possible to put a text storage object into an inconsistent state—for example, by changing the font of a range to one that doesn’t support the characters in that range (such as using a Latin font for Kanji text).
