AdditionalItemIdType

An AdditionalItemId represents a product identification code of some sort. According to the GS1 standard this is mostly a GTIN of 8-14 digits, but it might be a Non-standard code for special use cases or it might be a PLU code for specific PLU use cases. It can also be a QR code or other machine registrable code or just an alternative SKU. This is also why several types are supported in Hii Retail

        - we know other identifiers than GTIN are required beyond the GS1 specifications.
