Has anybody found any documentation about concrete protocols? (That was supposed to be one new feature in Objective-C 2.0.)

Protocols in Objective-C 2.0 can have methods that are marked as @required and @optional for classes that conform to the protocol, making them useful for describing delegate methods where protocols weren't before.

Is this what you're referring to?
