You are right, you cannot use it for non-file resources. Every FileSelector is a ResourceSelector, so technically Ant might allow such a construct, but it wouldn't work - as <different> restricts itself to file-system resources. It would probably be possible to generalize <different> to arbitrary resources, but this hasn't happened so far. If we were to allow a non-file-system target (like a target ResourceCollection) the lookup "find the target resource if it exists" could become expensive as our ResourceCollections are really only iterators - so we'd do a linear search inside of the target collection. In the case of a target ZIP archive, we'd re-open the ZIP and scan it for each and every resource encountered by the selector..
