/* The kind of a Xinfo data set is determined by Xinfo_kind. Each
* Xinfo_kind consists of a major_id and an minor_id. The major id
* defines the object group (e.g. process, entit/architecture,
* package, type) while the minor_id determines a subelement of an
* object group. E.g. major_id might be set to "type" and minor_id
* might be set to "array type". */
