      Simple DC XML Schema, 2002-10-09
      by Pete Johnston (p.johnston@ukoln.ac.uk),
      Carl Lagoze (lagoze@cs.cornell.edu), Andy Powell (a.powell@ukoln.ac.uk),
      Herbert Van de Sompel (hvdsomp@yahoo.com).
      This schema defines terms for Simple Dublin Core, i.e. the 15
      elements from the http://purl.org/dc/elements/1.1/ namespace, with
      no use of encoding schemes or element refinements.
      Default content type for all elements is xs:string with xml:lang
      attribute available.

      Supercedes version of 2002-03-12.
      Amended to remove namespace declaration for http://www.w3.org/XML/1998/namespace namespace,
      and to reference lang attribute via built-in xml: namespace prefix.
      xs:appinfo also removed.
