             Summary: Ability to Allow Empty and Duplicate Tika Values for XML Elements
                 Key: TIKA-1133
                 URL: https://issues.apache.org/jira/browse/TIKA-1133
             Project: Tika
          Issue Type: Improvement
          Components: parser
    Affects Versions: 1.3
            Reporter: Ray Gauss II
            Assignee: Ray Gauss II
