Amendment 1 (2025-10) includes
Subclause 6.11.1
Replace:
The number of SingleItemTypeReferenceBoxes with the box type 'drgn' and with the same value of from_item_ID shall not be greater than 1.
With:
The number of SingleItemTypeReferenceBox or SingleItemTypeReferenceBoxLarge entries with the box type 'drgn' and with the same value of from_item_ID shall not be greater than 1.
However there is no subclause 6.11.1 (or 6.11).
Probably this was intended to reference Subclause 11.3.3.1.
