Chapter 3.9. Footnotes

Text can be marked as footnote by enclosing the text with the <span class="footnote"> ... </span> element. In the following example, the text "This text is a footnote" appears as footnote:
<p>An example<span class="footnote">This text is a footnote</span>.
Some more text in the paragraph.</p>
In HTML output the footnotes are collected and output at the appropriate location, e.g. at the end of each chapter. Furthermore in HTML output footnotes are active links. In print output the footnotes are shown at the end of the page where the footnote reference is located.
Numbering format
By default footnotes are numbered with decimal numbers. However, a different numbering format (for example i, ii, iii, iv,...) can be set in the output-configuration (see Section 2.6.2.1.2, “Numbering settings”).
Creating multiple references to the same footnote
You can insert further references at different positions within the content to an existing footnote. To do this, an identifier has to be assigned to the footnote. A reference to the same footnote can then be created by creating a footnote with text {see:#id}, where id is the identifier of the footnote to be referenced. In the following example, the ID "my_note" is assigned to the footnote in the first paragraph. Furthermore, a second reference to the same footnote exists in the second paragraph:
<p>An example<span class="footnote" id="my_note">This text is a
footnote</span>.</p>
<p>A reference to the same
footnote<span class="footnote">{see:#my_note}</span>.</p>
