 ### Bounding Box Columns
 
-A bounding box column MUST be a Parquet group field with 4 child fields named `xmin`, `xmax`, `ymin`, and `ymax`. For three dimensions the additional fields `zmin` and `zmax` MAY be present but are not required. The fields MUST be of Parquet type `FLOAT` or `DOUBLE`. The repetition of a bounding box column MUST match the geometry column's [repetition](#repetition). A row MUST contain a bounding box value if and only if the row contains a geometry value. In cases where the geometry is optional and a row not contain a geometry value, the row MUST NOT contain a bounding box value.
