### Describe the bug, including details regarding any error messages, version, and platform. In the Columnar format, the handling of null values in the REE type is not described properly. - The null count of the parent array should be 0, since the parent has no validity bitmap (and there is a general assumption in arrow code that a non-zero null count means the standard validity bitmap is present) - The document only indirectly describes how Null values are encoded Thanks @tustvold for catching this!
