+ *
+ *   NAME
+ *  BufferNode -- Class to maintain the tree of bufferred elements
+ *
+ *   FUNCTION
+ *  One BufferNode object represents a bufferred element in the document
+ *  wrapper component.
+ *  All BufferNode objects construct a tree which has the same structure
+ *  of all bufferred elements. That is to say, if one bufferred element is
+ *  an ancestor of another bufferred element, then the corresponding
+ *  BufferNode objects are also in ancestor/descendant relationship.
+ *  This class is used to manipulate the tree of bufferred elements.
+ *
+ *   HISTORY
+ *  05.01.2004 -    implemented
+ *
+ *   AUTHOR
