# Tag Validation Mode

1. Can be applied at the presentation level or slide level (the lowest level takes precedence).
2. Select between the two modes: [#strict](#strict "mention") or [#lenient](#lenient "mention")

### Strict

1. The system validates all tags defined in the payload.
2. If any tag is missing from the template.pptx, a `VALIDATION_ERROR` (400) is returned.

    ]
  }
}

{% endcolumns %}

### Lenient

1. Missing tags are skipped without interrupting execution.
2. This mode is useful when working with templates that have optional placeholders or evolving structures.
