### 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

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

            }
          }
        }
      } + Channel + Standard
  }
}

sealed class SocketMode

object Channel : SocketMode() {
  override fun toString(): String = "Channel"
}

object Standard : SocketMode() {
  override fun toString(): String = "Standard"
}

data class TlsInstance(
  val provider: Provider,
  val protocol: Protocol,
  val tlsVersion: TlsVersion,
