  - `as_of` string, nullable
  - `attribution` string[], required
  - `codes` string[], required: The trouble codes the summary names.

  - `document` BulletinDocument: Where NHTSA's copy of a bulletin's document is expected to be.
    - `alternate_url` string, required: The address to try when `url` answers "not found": NHTSA files documents under one of two endings, and the data does not say which.
    - `confirmed` boolean, required: Always `false`. The addresses are built from a rule that held for a sample of documents; this API has not asked NHTSA for this one.

  - `url` string, required
  - `vehicles` BulletinVehicle[], required
    - `make` string, required: The make and model as the source words them.
    - `match` string, nullable: `exact`, `base` or `curated`; `null` when the model is not in the catalog for these years.
    - `model` string, required
    - `vehicle_ids` string[], required: The vehicle id of each model year in the run, when it matched.
    - `year_from` integer, nullable: The first and last model year of a run, inclusive. Both `null` when the bulletin gave no model year.
