> The documentation for {{list<ColumnOrder> column_orders}} states that "Each sort order corresponds to one column, determined by its position in the list, matching the position of the column in the schema."
> However, in reality, while the order of elements in these two lists (schema and sort order) are the same, only leaf nodes are represented in the list of sort orders, so the positions do *not* match.
