On utilise alors l'argument `deprecated=True` de `Query` :

{* ../../docs_src/query_params_str_validations/tutorial010.py hl[18] *}

La documentation le présentera comme il suit :

## Pour résumer

    val byteArray = source.readByteArray(bytesLeft)
    return BigInteger(byteArray)
  }

  fun readLong(): Long {
    if (bytesLeft !in 1..8) throw ProtocolException("unexpected length: $bytesLeft at $this")

    var result = source.readByte().toLong() // No "and 0xff" because this is a signed value!
    while (byteCount < limit) {
      result = result shl 8

Então você passa o parâmetro `deprecated=True` para `Query`:

{* ../../docs_src/query_params_str_validations/tutorial010.py hl[18] *}

Na documentação aparecerá assim:

## Recapitulando

Você pode adicionar validações e metadados adicionais aos seus parâmetros.
