In print or 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.
<caption> contains the entire, visible textual description of a table, figure, or similar object, but does not typically include the figure or table number, since this will typically be generated on display. If needed in the text, such numbers will be tagged as <label>s. The text of the caption includes any separately tagged <title> and as many paragraphs of information as needed. It may include legends, which are not identified as a separate element in this 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, since 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.
