      DCMES 1.1 XML Schema
      XML Schema for http://purl.org/dc/elements/1.1/ namespace

      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.

            This is the default type for all of the DC elements.
            It permits text content only with optional
            xml:lang attribute.
            Text is allowed because mixed="true", but sub-elements
            are disallowed because minOccurs="0" and maxOccurs="0" 
            are on the xs:any tag.

    	    This complexType allows for restriction or extension permitting
            child elements.
