Alternative Hierarchy
Some situations may require components to be rendered in an alternative hierarchy than the polyhierarchy specified by the | is a | relationships in SNOMED CT. The diagram below Illustrates how the three attributes referencedComponentId, targetComponentId and order are used to create an alternative hierarchical order of some of the concepts from the subtype hierarchy.
