33  * - Tag data and most sets cannot be saved.
34  * - For blocks, geometry sets, and parallel partitions, the
35  * sets are saved but the IDs may be lost.
36  * - File format does not support general polygons or polyhedra.
37  * - File format does not support higher-order volume elements
38  * other than TET10 and HEX27.
