/**
* MODULE NOTES:
* @update  gess 7/20/98
*
* This interface defines standard interface for DTD's. Note that this
* isn't HTML specific. DTD's have several functions within the parser
* system:
*      1) To coordinate the consumption of an input stream via the
*      parser
*      2) To serve as proxy to represent the containment rules of the
*      underlying document
*      3) To offer autodetection services to the parser (mainly for doc
*      conversion)
