Portanto, se você quiser receber atualizações parciais que possam omitir todos os atributos, precisará ter um modelo com todos os atributos marcados como opcionais (com valores padrão ou `None`).

Para distinguir os modelos com todos os valores opcionais para **atualizações** e modelos com valores obrigatórios para **criação**, você pode usar as ideias descritas em [Modelos Adicionais](extra-models.md){.internal-link target=_blank}.

Entonces, si deseas recibir actualizaciones parciales que puedan omitir todos los atributos, necesitas tener un modelo con todos los atributos marcados como opcionales (con valores por defecto o `None`).

Para distinguir entre los modelos con todos los valores opcionales para **actualizaciones** y modelos con valores requeridos para **creación**, puedes utilizar las ideas descritas en [Modelos Extra](extra-models.md){.internal-link target=_blank}.

     *            SPN of the target system, optional

Pero para este ejemplo, usaremos un documento HTML muy simple con algo de JavaScript, todo dentro de un string largo.

Esto, por supuesto, no es lo ideal y no lo usarías para producción.

En producción tendrías una de las opciones anteriores.

Pero es la forma más sencilla de enfocarse en el lado del servidor de WebSockets y tener un ejemplo funcional:

The "Metadata" section contains a single version, encoded in similar fashion as each version in the `Versions` array
of the previous version.

## Inline Data

Inline data is optional. If no inline data is present, it is encoded as 0 bytes.
