<!--
  This is the Shared DTD for SVG 1.0 (draft 20000303). It contains the
  element, attribute and entities definitions which are common to the 
  DTD for Stylable SVG and the DTD for Exchange SVG.

  The only purpose of the Shared DTD is to serve as a single definition for
  the definitions of elements, attributes and entities that are common to
  the DTD for Stylable SVG and the DTD for Exchange SVG.
  The Shared DTD should not be used directly; instead, use either the
  DTD for Stylable SVG or the DTD for Exchange SVG.

  The specification for SVG that corresponds to this DTD is available at:

    http://www.w3.org/TR/2000/03/WD-SVG-20000303/
