 * [ ] Add structs/fields to `nomad/structs` package
   * Validation happens in this package and must be implemented
   * Implement other methods and tests from `api/` package
+  * Note that analogous struct field names should match with `api/` package
 * [ ] Add conversion between `api/` and `nomad/structs` in `command/agent/job_endpoint.go`
 * [ ] Add check for job diff in `nomad/structs/diff.go`
