As part of my document objects, I have to deal with a custom object, for which I would also like to implement undo/redo. I know NSResponder has undo/redo features, but how should I implement this for a custom object?

I would like to implement undo/redo for a model object which in turn is also a ivar backed property of a document object. I'm already using the document's undo manager to undo/redo setting the model object property. Once the property is set, the application has features to change properties of the model object. I'm not sure how to implement undo/redo for the changes of the model object's properties and ivars.
