      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.
