The ITEM_STRUCTURE_LIST category holds definitions of matrices and vectors that can be associated with data items. A component of the key for this category is _item_type_list.code, which is referenced by _item_structure.code to assign a structure type to a data item. The definition of a structure involves the specification of a length for each dimension of the matrix structure. The combination of items _item_structure_list.code and _item_structure_list.index forms the key for this category. The latter index item is the identifier for the dimension, hence multiple unique dimensions can be specified for each structure code. The length of each dimension is assigned to _item_structure_list.dimension.
