> On TIKA-1678, I was trying to generate a test PDF that had a dc:title in the XMP with XMPBox from PDFBox's trunk.  I modified the code from CreatePDFA by adding this:
> {code}
> DublinCoreSchema dc = xmp.createAndAddDublinCoreSchema();
> dc.setTitle("this is the title");
> {code}
> The generated PDF doesn't appear to have a compliant dc:title entry in the XMP.  
> [~tilman] noted the divergence from the standard [here|https://issues.apache.org/jira/browse/TIKA-1678?focusedCommentId=14634045&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14634045].
> What PDFBox does:
> {code}
>       <dc:title>
>         <rdf:Alt>
>           <dc:li>this is the title</dc:li>
>         </rdf:Alt>
>       </dc:title>
> {code}
> It should be:
> {code}
>           <dc:title>
>             <rdf:Alt>
>               <rdf:li xml:lang="x-default">this is the title</rdf:li>
>             </rdf:Alt>
>           </dc:title>
> {code}
> Error message from the PDF-Tools validator:
> {quote}
> '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.
> {quote}
