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#

...

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.
