Additional material added to — and usually following — an article, for example, a table (or set of tables), maps, notes, etc. This is ancillary or supporting material, not a direct continuation of the text of an article.
In previous versions of this tag set, a <title> element was required on each appendix. A title was considered to be the basic requirement for producing an automated Table of Contents for online viewing of an article; so a title was required. However, as nice as it would be to keep that requirement, this is a conversion target tag set, and conversion experience has shown that not all appendices in the wild have either titles (e.g., “Conversion Tables)” or labels (“Appendix 6”). Without true section-level headings it will be difficult to create automatic Tables of Contents and high-quality web and print displays.
