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