Description of the new Feature/Bugfix
To fix the bug, I improved multilingual support by refining the handling of language-alternative (
LangAlt) title and description in the Dublin Core Schema using the standard-conforming syntax with the required (at least for PDF/A-1)xml:langattribute. Further I fixed a typo in thepdf:Keywordstag in the PDF Schema.Related Issue: #971
Unit-Tests for the new Feature/Bugfix
Compatibilities Issues
All existing methods behave as before. I only added two addtional methods for multilingual titles and descriptions. Even when using the existing API the output will slightly differ, because
xml:langis now always added todc:titleanddc:description.Your real name
