### Input Model in Docs { #input-model-in-docs }

You can confirm that in the docs, the `description` field doesn't have a **red asterisk**, it's not marked as required:

<div class="screenshot">
<img src="/img/tutorial/separate-openapi-schemas/image01.png">
</div>

### Model for Output { #model-for-output }

But if you use the same model as an output, like here:

          # retainVersions: 0 # (default) delete all versions of the object. This option is the fastest.
          # retainVersions: 5 # keep the latest 5 versions of the object.
  
    - type: deleted # objects with delete marker as their latest version
      name: NAME # match object names that satisfy the wildcard expression.
      olderThan: 10h # match objects older than this value (e.g. 7d10h31s)
