 * @update  gess 4/1/98
 * This class is defines the basic interface between the
 * parser and the content sink. The parser will iterate
 * over the collection of tokens that it sees from the
 * tokenizer, coverting each related "group" into one of
 * these. This object gets passed to the sink, and is
 * then immediately reused.
 * If you want to hang onto one of these, you should
 * make your own copy.
