/*
 * STRUCT: SE_GENERAL_HIERARCHY_SELECT
 *
 *   Used to build up the SE_HIERARCHY_SELECT_PARAMETERS struct.
 *
 *   Indicates at a 'high level' whether any components of the given
 *   <Aggregate Geometry> and <Aggregate Feature> objects should be traversed.
 *
 *   For 'types' (i.e., DRM classes) of <Aggregate Feature>/<Aggregate
 *   Geometry> (referred to as "hierarchies" in these comments) for which
 *   inclusion rules can be specified:
 *
 *     If a 'type' of hierarchy object has an SE_EXCLUDE_ALL value in this
 *     struct, then the rules within the SE_HIERARCHY_SELECT_PARAMETERS values
 *     for that type of hierarchy object are not evaluated.  Objects of that
 *     hierarchy type and the components of those hierarchy objects are always
 *     excluded from the search space of the iterator.
 *
 *     If a 'type' of hierarchy object has an SE_INCLUDE_ALL value in this
 *     struct, then the rules within the SE_HIERARCHY_SELECT_PARAMETERS values
 *     for that type of hierarchy object are not evaluated.  Objects of that
 *     hierarchy type and the components of those hierarchy objects are always
 *     included in the search space of the iterator.
 *
 *     If a 'type' of hierarchy object has an SE_EVALUATE_RULES value in this
 *     struct, then the rules within the SE_HIERARCHY_SELECT_PARAMETERS values
 *     for that type of hierarchy object are evaluated for each hierarchy
 *     component attached to the hierarchy object.  Only hierarchy components
 *     whose link attached data pass the rules are included in the
 *     search space of the iterator.
 *
 *   For types of hierarchies for which inclusion rules cannot be specified:
 *
 *     If a 'type' of hierarchy object has a value of SE_FALSE then all
 *     objects of that hierarchy type and the components of those hierarchy
 *     objects are always excluded from the search space of the iterator.
 *
 *     If a 'type' of hierarchy object has a value of SE_TRUE then all
 *     objects of that hierarchy type and the components of those hierarchy
 *     objects are always included in the search space of the iterator.
