/**
* Represents an end note footnote.
* End notes are collected at the end of a document or section rather than
* at the bottom of a page.
* Create a new footnote using {@link XWPFDocument#createEndnote()} or
* {@link XWPFEndnotes#createFootnote()}.
* The first body element of a footnote should (or possibly must) be a paragraph
* with the first run containing a CTFtnEdnRef object. The {@link XWPFFootnote#createParagraph()}
* and {@link XWPFFootnote#createTable()} methods do this for you.
* Footnotes have IDs that are unique across all footnotes in the document. You use
* the footnote ID to create a reference to a footnote from within a paragraph.
* To create a reference to a footnote within a paragraph you create a run
* with a CTFtnEdnRef that specifies the ID of the target paragraph.
* The {@link XWPFParagraph#addFootnoteReference(XWPFAbstractFootnoteEndnote)}
* method does this for you.
