      Description

      According to XMP specification properties may have qualifiers. In our scenario we used xmp:Identifier element from XMP Basic Schema holding an array of text strings. An array item may be qualified with xmpidq:Scheme:

      <rdf:Description rdf:about=""
                       xmlns:xmp="http://ns.adobe.com/xap/1.0/"
                       xmlns:xmpidq="http://ns.adobe.com/xmp/Identifier/qual/1.0/">
        <xmp:Identifier>
          <rdf:Bag>
            <rdf:li rdf:parseType="Resource">
              <rdf:value>A</rdf:value>
              <xmpidq:Scheme>http://archyvai.lt/pdf-ltud/2013/level/</xmpidq:Scheme>
            </rdf:li>
          </rdf:Bag>
        </xmp:Identifier>
      </rdf:Description>
      

      DomXmpParser fails when parsing XMP containing such qualifiers:

      org.apache.xmpbox.xml.XmpParsingException: Schema is not set in this document : http://www.w3.org/1999/02/22-rdf-syntax-ns#
      	at org.apache.xmpbox.xml.DomXmpParser.checkPropertyDefinition(DomXmpParser.java:787)
      	at org.apache.xmpbox.xml.DomXmpParser.parseLiDescription(DomXmpParser.java:508)
      	at org.apache.xmpbox.xml.DomXmpParser.parseLiElement(DomXmpParser.java:449)
      	at org.apache.xmpbox.xml.DomXmpParser.manageArray(DomXmpParser.java:407)
      	at org.apache.xmpbox.xml.DomXmpParser.createProperty(DomXmpParser.java:309)
      	at org.apache.xmpbox.xml.DomXmpParser.parseDescriptionRoot(DomXmpParser.java:267)
      	at org.apache.xmpbox.xml.DomXmpParser.parse(DomXmpParser.java:199)
      	at org.apache.xmpbox.TestXMPWithDefinedSchemas.main(TestXMPWithDefinedSchemas.java:66)
      ...
      

      It appears it failed on rdf:value element as org.apache.xmpbox.type.TypeMapping class is not aware about http://www.w3.org/1999/02/22-rdf-syntax-ns# standard namespace.
