Ampleforth could use reference/footnote/citation/bibliography support

[gbracha]

This may be start our as a variant of HTML links or HyperlinkFragments referencing a list of papers, but we'd want nice naming or numbering automatically, and transcluding individual entries from something akin to bib files . Importing .bib files would be super nice.
You'd want to expand the citation in place on demand, as well as a(n optional) list the complete Bibliography at the end as in print (the latter is good for having a complete list of references, and for printing versions for submitting papers. Submitting has other issues though - page numbers, and generally the requirements venues have for mainstream formats.

Likewise, footnotes. In principle they make no sense in an online format, just as page numbers don't. But they make sense when printing out.
