Within a bibliographic reference (<element-citation> or <mixed-citation>), the <trans-source> element contains the title of a journal, book, conference proceedings, etc., that is the source of the cited material, but with the source name given in a different language from the source as given in the <source> element. For example, if a journal’s title is originally in French, the <source> element would contain the French title, and the <trans-source> might contain the equivalent English title.
