The link that renders with footnotes to jump back to the main content uses the "rev" attribute, which has been removed in HTML5 (see http://www.google.com/search?sourceid=chrome&ie=UTF-8&q=html5+rev+attribute). The recommendation is to use the "rel" attribute with a name meaning the opposite of it's partner "rel" attribute. Therefore, since the footnote link has rel="footnote" I changed the return link to rel="reference". Can you think of a better value for this?
Replace rev attribute for HTML5 compatibility
Looks good to me.
Just noticed this has been sitting open for awhile. Can someone please either accept it or close it so I can update from my fork? Thank you!
