1) Subclassing NSDocumentController and implementing openDocumentWithContentsOfURL:display:error:. This almost works perfectly. I can detect .foo files and do my special handling, but when I return nil, Cocoa 'helpfully' displays a generic error message, which I do not want. Even overriding willPresentError: to return nil doesn't suppress the alert.

Create an error with domain==NSCocoaErrorDomain and code==NSUserCancelledError and return nil from openDocumentWithContentsOfURL:display:error:.
