Subordinate heading or title for a book or for one of its structural elements, such as a <book-part>
Conversion Note: 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.
