Additional information tied to a particular location in the text. This material is not considered to be part of the body of the text, but is an aside used instead of, in addition to, as a source for, or as a commentary on either some body text or on an element in the metadata.
A footnote <fn> usually contains material that cannot stand alone: material that is related to a word, phrase, table cell, or paragraph already in the basic textual material and thus is tied to a particular location in the text or to a structure in the text, such as a table or figure. Thus footnotes may appear within paragraphs of text in the narrative body or inside structures such as figures, boxed-text, and tables as part of that structure.
Footnotes may be collected together for display, inside a grouping element (<fn-group>).
Display of Footnotes
In print, footnotes are traditionally displayed:
- at the bottom (foot) of a printed page,
- at the bottom of the structure such as a table (table notes) or figure (figure notes) they are inside, or
- in a list at the end of a standards document (which are sometimes called end notes; this grouping is tagged with the <fn-group> element).
Referencing a Footnote
To describe a footnote that is not in the same language as the original standards document (for example, a German or Latin footnote for a document in English), use the @xml:lang attribute on the footnote.
Best Practice Footnote Placement
Within a document, footnotes that are specific to a structure, such as a table of figure, should be placed inside that structure. Footnotes in the narrative text should either be placed:
- Throughout the XML, at the place to which they are linked, or
- Grouped at the end of the document.
