Footnotes are placed at the bottom of a page to display additional information, comments or citations. Generally, the footnote marker in the text is represented by a superscripted number.
We just published a prototype sample that shows how to implement fully featured footnotes using TextFields and TextFrames. A TextField is inserted for each footnote and holds the formatted text in it's Name property. This guarantees the consistency of inserted TextFields and allows you to save the document using the internal TX Text Control format and RTF.
