For example:
Here is a footnote reference[^1], and another[^longnote].
[^1]: Here is the footnote.
[^longnote]: Here's one with multiple blocks.
Subsequent paragraphs are indented to show that they
belong to the previous footnote.
* item1
* item 2
**More** text
<em>italic</em>
Here is a footnote reference[1], and another[2].
