List of figure call-out descriptions.
The call-out description list can be part of the information module text (in which case this element is used), or of the graphics (do not use this element). If it is part of the graphics it will not be accessible through SGML, and it might not be readable, depending on media, resolution, and graphics format. It will, however, be positioned inside the graphics area. If it is part of the SGML text, it will be positioned in the normal flow of text, possibly after the figure.
