Wrapper element for the textual description that is associated with (part of) a Figure, Table (XHTML table model), etc. This is the title for the figure or the description of the figure that prints or displays with the figure.
In print or on display, a caption is usually recognizable because it is not part of the ordinary text flow; it sits just under, above, beside, or in the same small window or page area as the tabular portions of the table or the graphical portions of the figure.
The <caption> element in this DTD Suite contains the entire, visible textual description of an object such as a table or figure, excepting the figure or table number. The text of the caption includes any separately tagged <title> that might be present and as many paragraphs of information as needed. It may include legends, which are not identified as a separate element in this DTD Suite.
The text of the caption does not include words such as “Figure 3.” or “Table 11-a”. These labels may not be present in the XML file, because many publishers choose to generate such text at display time; but if they are in the source XML, they may be preserved using the <label> element.
Conversion Note: In many journal articles, a distinction is made between the caption of a figure/table/etc. and its title. There may be two separate tags (<caption> and <title>), or the first sentence of the caption may be set off typographically from the rest of the caption to indicate that it is a title, for example, the first sentence may be italic or bold. In either case, if it is obvious that the figure/table/etc. contains both a title and a caption, both the title and the caption should be tagged during conversion, and the title should be moved inside the caption if it is outside.
