If you want to call it "container" or not is up to you. The "@" notation is similar to the Unified diff format: http://en.wikipedia.org/wiki/Diff#Unified_format - which supports multiple files. Nobody every suggested to create a diff for each file separately, and zip them or use multipart/*. It's always simply one file. Also, both zip and multipart/* don't support json metadata. Then, zip and multipart/* are vastly more complex solutions. Regards, Thomas
