 Each subgroup may also contain a (nested) `particles_group` subgroup, in order to subdivide the group of particles into an organizational hierarchy. As with the overall `particles_group` container, the groups contained within `particles_group` must not *partition* the particles within this group (i.e., overlapping or non-complete groupings are allowed). However, particle groups *must* contain particles already contained within the parent `particles_group` (i.e., subgroups must be a subset of the grouping at the previous level of the hierarchy).
 
 Note that typically the `particles_group` hierarchy ends at the level of individual particles (i.e., individual particles are not stored, since this information is already contained within the `particles` group).
