// .NAME vtkCompositeDataSet - abstact superclass for composite (multi-block or AMR) datasets
// .SECTION Description
// vtkCompositeDataSet is an abstract class that represents a collection
// of datasets (including other composite datasets). This superclass
// does not implement an actual method for storing datasets. It
// only provides an interface to access the datasets through iterators.
// .SECTION See Also
// vtkCompositeDataIterator
