It is compatible with readers expecting an integer data type. An
enumerated-type dataset can be read using, e.g., H5T_NATIVE_INT as
the memory datatype.

For writing, however, the memory datatype needs to be an enumerated
type. A program extending an existing enumerated-type dataset needs
to be aware of this.
