This is a problem that's been discussed on the dev forums since the early days of security-scoped bookmarks. How about implement -writeToURL:… so that if the document doesn't have a URL yet, you first create a placeholder file, before overwriting it with the real data? As I understand it, the important thing for bookmarks to work is to attach some metadata to the document, identifying it.
