Example:

// Insert some text and mark it with a footnote with the IsAuto property set to "true" by default,

// which will be used in place of the number "2" and set "IsAuto" to false.
builder.write("This text will be referenced by an endnote.");

// Footnotes always appear at the bottom of their referenced text,
// so this page break will not affect the footnote.
// On the other hand, endnotes are always at the end of the document
// so that this page break will push the endnote down to the next page.

Example:

// mark after the text that it references and create an entry below the main body text at the bottom of the page.
// This entry will contain the footnote's reference mark and the reference text,
// which we will pass to the document builder's "InsertFootnote" method.

Footnote footnote = builder.insertFootnote(FootnoteType.FOOTNOTE, "Footnote text.");

// If this property is set to "true", then our footnote's reference mark
// will be its index among all the section's footnotes.
// This is the first footnote, so the reference mark will be "1".
