Tag Validation Mode

• Can be applied at the presentation level or slide level (the lowest level takes precedence).

• Select between the two modes: Strict or Lenient

Strict

• The system validates all tags defined in the payload.

• If any tag is missing from the template.pptx, a VALIDATION_ERROR (400) is returned.

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

Lenient

• Missing tags are skipped without interrupting execution.

• This mode is useful when working with templates that have optional placeholders or evolving structures.
