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.
