 *AtkRelationType:
 *@ATK_RELATION_NULL:
 *@ATK_RELATION_CONTROLLED_BY: Indicates an object controlled by one or more target objects.
 *@ATK_RELATION_CONTROLLER_FOR: Indicates an object is an controller for one or more target objects.
 *@ATK_RELATION_LABEL_FOR: Indicates an object is a label for one or more target objects.
 *@ATK_RELATION_LABELLED_BY: Indicates an object is labelled by one or more target objects.
 *@ATK_RELATION_MEMBER_OF: Indicates an object is a member of a group of one or more target objects.
 *@ATK_RELATION_NODE_CHILD_OF: Indicates an object is a cell in a treetable which is displayed because a cell in the same column is expanded and identifies that cell.
 *@ATK_RELATION_FLOWS_TO: Indicates that the object has content that flows logically to another
 *  AtkObject in a sequential way, (for instance text-flow).
 *@ATK_RELATION_FLOWS_FROM: Indicates that the object has content that flows logically from
 *  another AtkObject in a sequential way, (for instance text-flow).
 *@ATK_RELATION_SUBWINDOW_OF: [not sure about this one, ask Peter]
 *@ATK_RELATION_EMBEDS: Indicates that the object visually embeds 
 *  another object's content, i.e. this object's content flows around 
 *  another's content.
 *@ATK_RELATION_EMBEDDED_BY: Inverse of %ATK_RELATION_EMBEDS, indicates that
 *  this object's content is visualy embedded in another object.
 *@ATK_RELATION_LAST_DEFINED:
