As far as I can tell, the exhibit attributes are designed solely to be
read by the exhibit JS library which creates special views of the
data.  The site embeds that library, and so it's part of the site.

The restrictions there are meant to restrict things like, for example,
embedding Microformats data with data-* attributes, with the intention
that they'll be read by spiders and other things outside of the page
author's control.
