An alternative or “different” version of a book title (or title of a book component such as a chapter), usually created so that it can be processed in a special way, for example, a short version of the title for use in a Table of Contents, an ASCII-only title for display on restricted devices, a right-running-head title for a print publication, etc.
Conversion Note: This element should not be used for either the translated title <trans-title> (which is an alternative version of a title in another language) or the subtitle <subtitle> (which is an addition to the title).
