The AtkRelationSet held by an object establishes its relationships
with objects beyond the normal \"parent\/child\" hierarchical
relationships that all user interface objects have.
AtkRelationSets establish whether objects are labelled or
controlled by other components, share group membership with other
components (for instance within a radio-button group), or share
content which \"flows\" between them, among other types of possible
relationships.
