      http://purl.org/dc/elements/1.1/ namespace Created 2008-02-11 Created by Tim Cole
      (t-cole3@uiuc.edu) Tom Habing (thabing@uiuc.edu) Jane Hunter (jane@dstc.edu.au) Pete Johnston
      (p.johnston@ukoln.ac.uk), Carl Lagoze (lagoze@cs.cornell.edu) This schema declares XML
      elements for the 15 DC elements from the http://purl.org/dc/elements/1.1/ namespace. It
      defines a complexType SimpleLiteral which permits mixed content and makes the xml:lang
      attribute available. It disallows child elements by use of minOcccurs/maxOccurs. However, this
      complexType does permit the derivation of other complexTypes which would permit child
      elements. All elements are declared as substitutable for the abstract element any, which means
      that the default type for all elements is dc:SimpleLiteral. </xs:documentation>
