+ *
+ * This is the base class for all type of objects that match these criteria:
+ * -they can not have child objects
+ * -they are only a reference to a primary key (which needs not to be in the
+ *  key ring)
+ *
+ * Do not create instances from this class. Use KGpgGroupMemberNode and
+ * KGpgSignNode as those represent the existing objects. This class exists
+ * only to get the hierarchy right.
