Annulling Nodes
When you annul a node, the node is removed from the parent, and, if it becomes an orphan, the orphan node is deleted. For example, if a node is annulled in one of several hierarchies where it exists, then the node is just removed from that hierarchy and other hierarchies where it had the same parent. If a node is annulled from its parent in the only hierarchy it exists in, then Annul results in the node being deleted.
