Short closing tags for UniqueNode parser

 I have been found this problem when parsed Unicode XML database with UniqueNode parser
For example:

      <char cp="0020" age="1.1" na="SPACE" JSN="" ..... na1="">
         <name-alias alias="SP" type="abbreviation"/>
      </char>
      <char cp="0021" age="1.1" na="EXCLAMATION MARK" JSN="" ..... na1=""/>
