No grouping semantics of any kind are defined by this RM4TM. This RM4TM requires all groups to be explicitly represented as nodes. Any other approach would open the possibility for knowledge about a group to fail to be connected to the single node whose subject is the group, and that would be contrary to the Subject Location Uniqueness Objective.
Better to include under node properties (parid0220).
