Inside a bibliographic reference (<citation>), the full title of a cited journal article.
The title is nearly always in the original language of publication, but a publisher or archive might choose to place all article titles in one language, such as English, and use the translated title element to hold the original title (Translated Title <trans-title>).
Within a bibliographic reference citation, a subtitle cannot be preserved separately. Some DTDs place it within the title; some leave it as untagged data characters within the text of the <citation>. Although this DTD Suite cannot enforce either structure, retrieval performance will be enhanced if the subtitle is placed into the <article-title> element in cited material, so this is considered best practice.
