The guide deems the traditional topostratigraphic framework obsolete, thus affecting the validity of the 'Latorp', 'Lanna' and 'Holen' limestones, as well as many other regional Ordovician units (for reference, topostratigraphy employs a mixture of lithologically and palaeontologically defined boundaries in stratigraphic units; Jaanusson 1960b).
