I agree - What you're trying to do doesn't fit well with the methods
you'd ordinarily override. The "standard" methods are built around the
assumption that the entire document is to be saved.

Try overriding the action methods -saveDocument:, and perhaps
-saveDocumentAs:, and/or -saveDocumentTo:, if your app supports those
operations.
