For HierarchyInfo elements, the LNum element contains the name of the property that provides the level ordinal positions of the hierarchy. The value is equivalent to the LEVEL_NUMBER property defined for axis rowsets in the OLE DB for OLAP specification.
For Member elements, the LNum element contains the zero-based ordinal position, from the root level of the hierarchy, of the member represented by the parent Member element. A value of zero represents the root level of the hierarchy.
