/**
 * @class   vtkCompositeDataWriter
 * @brief   legacy VTK file writer for vtkCompositeDataSet
 * subclasses.
 *
 * vtkCompositeDataWriter is a writer for writing legacy VTK files for
 * vtkCompositeDataSet and subclasses.
 * @warning
 * This is an experimental format. Use XML-based formats for writing composite
 * datasets. Saving composite dataset in legacy VTK format is expected to change
 * in future including changes to the file layout.
