  Defines a hierarchy in a dimension.  
  
## Syntax  
  
```xml  
  
<Hierarchies>  
   <Hierarchy xsi:type="Hierarchy">...</Hierarchy> <!-- ancestor: Dimension -->  
   <!-- or -->  
   <Hierarchy xsi:type="CubeHierarchy">...</Hierarchy> <!-- ancestor: CubeDimension -->  
   <!-- or -->  
   <Hierarchy xsi:type="PerspectiveHierarchy">...</Hierarchy> <!-- ancestor: PerspectiveDimension -->  
   <!-- or -->  
   <Hierarchy xsi:type="MeasureGroupHierarchy">...</Hierarchy> <!-- ancestor: RegularMeasureGroupDimension -->  
</Hierarchies>  
```
