     "DTD for nsgmls
      Some systems (including the popular nsgmls parser) may not be able
      to process files using 'plane 1' characters which have Unicode
      numbers higher than #xFFFF. The versions of the DTD provided here
      incorporate the modifications mentioned above, but the high
      characters are replaced by the equivalent mchar construct
      <mchar name="..." /> this allows the DTD to be read and for MathML
