Description

tilman asked that I open two separate issues for the finding in TIKA-1678 that XMPBox is not generating a valid dc:title entry in the XMP. This issue is meant to track preflight's failure to detect this problem.

What PDFBox does:

      <dc:title>
        <rdf:Alt>
          <dc:li>this is the title</dc:li>
        </rdf:Alt>
      </dc:title>

It should be:

          <dc:title>
            <rdf:Alt>
              <rdf:li xml:lang="x-default">this is the title</rdf:li>
            </rdf:Alt>
          </dc:title>

Error message from the PDF-Tools validator:

'dc:li' is not allowed in arrays. The elements must be rdf:li or rdf:_N, where N is a positive number.
There is only one RDF resource allowed in XMP.
