As far as I understand complication arises from complexity of model building programs. You may have many coordinate sets (not necessarily with same space group or even related ones, you may have many electron maps, they may be related to one or many coordinate sets). Ligand name that is valid for one set may not be valid for another set. Only way I see with my limited understanding of the problem is to have dictionary attached to each coordinate set or related coordinate sets. In some sense similar to namespaces.
