Label (Of a Figure, Reference, Etc.)


The number and any prefix word associated with, for example, the title or the caption of a <fig>, such as “Figure 3.” or “Exhibit 2.”. This element is also used for the number or symbol used as a prefix character for a footnote and placed at the place of the footnote reference.


This element can be used to preserve the prefix number or label of an element, for example, for a reference or citation “25.” or “[Lapeyre 2002]”. This can be useful when reconstructing untagged cross references.

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>).
<fig id="bid.37">
<caption><title>A GenBank CON entry for a complete 
bacterial genome.</title>
<p>The information toward the <italic>bottom</italic> of 
the record describes how to generate the complete genome 
from the pieces.</p>
