<index-title-group> Index Title Group

Container element to hold the various titles for a structured Index (or a subdivision of such an Index).

Usage/Remarks

This is very similar to BITS <title-group>, but made specific for the Index elements, so that the article-level or document-part-level <title-group> can be modified without consequences to this element, and this title group also can change freely, without side effects.
Related Elements
In the metadata for a book or book-part, there are several elements concerned with the title of a book or a book component. Such titles are contained within container elements: <book-title-group> (inside the <book-meta> and used only for the book titles), <title-group> (inside book parts such as chapters), <index-title-group> (inside an Index), or the <toc-title-group> (inside a Table of Contents).
