<p>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.</p>
