Translation and localization
DITA has features that facilitate preparing content for translation and working with
         multilingual content, including the @xml:lang attribute, the
         @dir attribute, and the @translate attribute. In addition,
            the <sort-as> and <index-sort-as> elements provide
            support for sorting in languages in which the correct sorting of an element requires
            text that is
            different from the base content of the element.
