I had forgotten about that. representedObject can be set this way to a plist type on NSCell instances. It would be possible to define an NSObject category property, say -myObjectName, backed by objc_setAssociatedObject and set that as a runtime attribute.

NSView implements NSUserInterfaceItemIdentification and this property can be set in Xcode 5 for a custom view. NSMenuItem also implements NSUserInterfaceItemIdentification but Xcode 5 doesn't provide direct access to this property. This would mean a different approach for menu and toolbar actions. It looks as if plain old -tag might win out after all.
