/**
 *AtkRelationType:
 *@ATK_RELATION_NULL: Not used, represens "no relationship" or an error condition.
 *@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: Indicates a subwindow attached to a component but otherwise has no connection in  the UI heirarchy to that component.
 *@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_POPUP_FOR: Indicates that an object is a popup for another object.
 *@ATK_RELATION_PARENT_WINDOW_OF: Indicates that an object is a parent window of another object.
 *@ATK_RELATION_DESCRIBED_BY: Indicates that another object provides descriptive information about this object; more verbose than ATK_RELATION_LABELLED_BY.
 *@ATK_RELATION_DESCRIPTION_FOR: Indicates that an object provides descriptive information about another object; more verbose than ATK_RELATION_LABEL_FOR.
 *@ATK_RELATION_NODE_PARENT_OF: Indicates an object is a cell in a treetable and is expanded to display other cells in the same column.
 *@ATK_RELATION_LAST_DEFINED: Not used, this value indicates the end of the enumeration.
