But these data items are all children pointing to their parent data items, and the style we have established in the dictionary is that we provide place holders for the children, but that those place holders only have _item.name and _item_mandatory.code specifiers. Ergo, these data items inherit their type from their parent, but we do not specify that in the same frame for each of them.
