Entity Hierarchy Level

DescriptionA group that contains all the elements that are at the same level in a hierarchy. Nodes that comprise a hierarchy level are not necessarily all child nodes of the same parent node. They are nevertheless placed on the same logical level in the hierarchy

For example:
All the cities in an administrative division hierarchy are part of the same level, regardless of what country or region they belong to.
