Why does Cocoa require a pointer to a pointer to NSDictionary here:

- (id)initWithHTML:(NSData *)data baseURL:(NSURL *)anURL
documentAttributes:(NSDictionary **)docAttributes

But only a single pointer here:

- (NSData *)RTFFromRange:(NSRange)aRange documentAttributes:(NSDictionary
*)docAttributes

In the first case it is passing you back a dictionary, by setting your pointer to point to it. In the second case, it is simply accessing a dictionary you give it, and is not changing your pointer's actual value.
