In this challenge, you will process shipment tracking updates generated by a legacy carrier system. Your goal is to map essential shipment details, correctly navigate XML namespaces, extract the most recent event to determine the shipment's current status, and reformat timestamps into the strict ISO-8601 standard required by the target logistics platform.
