    Update the statistics held in static data. We don't bother to sychronize, on the basis that it doesn't matter if the stats are wrong.
    
    Parameters:
    
    numberOfNodes - the number of (non-attribute, non-namespace) nodes
    
    numberOfAttributes - the number of attribute nodes
    
    numberOfNamespaces - the number of namespace bindings (deltas on namespace nodes)
    
    chars - the number of characters in text nodes
  - toString
