The <references> and <ref> tags have been amazing. However, on some articles,
I've seen people use these for footnotes instead of references, which is fine,
unless the article needs BOTH footnotes AND references. So what I suggest is a
separate <footnotes> and <note> tags, that will function very similarly to
references, though perhaps with a different rendering of the link, to make it
look different, e.g. a, b, c instead of 1, 2, 3.
Most importantly, the <note> tag would also allow <ref> tags within it.
