HierarchyParameterAttributeKey: Integer;
The HierarchyParameterAttributeKey property determines the attribute key, which values are used to select alternative hierarchy.
It is relevant if the HierarchyTypeSource property is set to AltHierarchySourceEnum.FromParam. As a property value specify key of the dictionary attribute, based on which the HierarchyParameterKey parameter is built. The attribute should return keys of the dictionaries that are alternative hierarchies for the Dictionary dictionary.
The property use is given in the example for IDefParameter.HierarchyParameterKey.
