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 or Lenient

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.

          },
          {
            "key": "month",
            "value": "FIVE"
          }
        ]
      }
    ]
  }
}

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.
