Test footnote and citation rendering

Paragraphs may contain footnote references (manually numbered[1], anonymous auto-numbered[3], labeled auto-numbered[2], or symbolic[*]) or citation references ([CIT2002], [DU2015]).

[1](1,2)

A footnote contains body elements, consistently indented by at least 3 spaces.

This is the footnote's second paragraph.

[2](1,2)

Footnotes may be numbered, either manually (as in[1]) or automatically using a "#"-prefixed label. This footnote has a label so it can be referred to from multiple places, both as a footnote reference ([2]) and as a hyperlink reference.

[3]

This footnote is numbered automatically and anonymously using a label of "#" only.

This is the second paragraph.

And this is the third paragraph.

[*]

Footnotes may also use symbols, specified with a "*" label. Here's a reference to the next footnote:[†].

[†]

This footnote shows the next symbol in the sequence.

[4]

Here's an unreferenced footnote, with a reference to a nonexistent footnote:[5].
