It is no longer correct to say "used to write this file or manifest". That sounds like it was copied from the old `ManifestFile` field (id=502) that was "Spec ID used to write", but that's no longer valid. Rather than writing an entire manifest with a single spec, files from any spec can now be written into a manifest. That means manifests themselves do not have a spec ID and instead specs are attached to individual content files. That's why a new ID is appropriate. I would use "Spec ID used to partition the file". -- This is an automated message from the Apache Git Service.
