<caption>
Caption of a Figure, Table, etc.
Container element for the textual description that is associated with an object (for
example, with a <fig> or <table-wrap>).
Remarks
A caption is a visible textual description of a table, figure, or similar object. 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 a table or the graphical portions of a figure. A <caption> may contain many kinds of text associated with
its object, for example, a title (tagged as <title>), a descriptive paragraph (tagged as <p>), or a legend (which is not identified as a separate element in this
Suite).
The text of the caption does not typically 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.
Best Practice: In many tag sets, a
distinction is made between the caption of a figure/table/etc. and its title. There may be
two separate elements (<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.

This element may be contained in:
Example 1
In a figure:
...
<sec id="bid.36">
<title>Microbial Genomes</title>
<p>... A CON entry, containing instructions on how to put
the pieces back together, is also made. The CON entry
contains descriptor information, such as source organism
and references, as well as a join statement providing
explicit instructions on how to generate the complete
genome from the pieces. The Accession number assigned
to the CON record is also added as a secondary Accession
number on each of the pieces that make up the complete
genome (see <xref ref-type="fig" rid="bid.37">Figure 2</xref>).
