Footnotes

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

The important points in this document are the following:

ΠWe set the number of columns for the main flow to 2.

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

Ž 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.

 Footnote's body is defined.
