Model-level commissioning event for a detergent DPP (no serial -- model-based per EU 2026/405).
Architecture: the event references identifiers by URI — GTIN in epcList, GLN in readPoint/bizLocation, party GLN in source/destination. Model-, location-, and party-level master data is served by the GS1 Digital Link / Web Vocabulary resolver when those URIs are dereferenced; it is NOT embedded in the event.
gs1:masterDataAvailableFor carries ONLY item/lot-level master data (e.g. countryOfOrigin, regulatoryInformation, harvestDate, EUDR plot geolocation). ilmd carries lot/instance data of the items this event creates. Observation extensions sit at event level.
