 * "forming" object plus the table object.  We create this special object to
 * save the following components of the nis_object:
 *	zo_name and zo_domain: replaced by just the length field of 0.  We had
 *		to keep the length field for backward compatibility.  If we
 *		ever change the object format, we should fix this.
 *	zo_owner and zo_group: we condensed it by abbreviating the common part
 *		shared between the table object and the entry object
 *	en_type: Avoided altogether
 *	zo_type and other en_data: Avoided altogether.
 *
 * XXX: If the definition of nis_object ever changes, this should be changed.
