A footnote is an out-of-line object composed from two elements: an fo:inline element used to insert a symbol in the document and a fo:footnote-body containing the text that the symbol is referring to.

 

Example of usage:

Output:

 

 

Key observations:

 

(1) The number of columns for the main flow has been set to 2.

(2) A special area ("xsl-footnote-separator" is a reserved name) is created to hold the separator between the footnotes and the document's body. This region is optional.

(3) The footnote object is declared, inline with the text. The first child element, fo:inline is used to format the number/symbol of the footnote.

(4) Footnote's body is defined.
