3.2.3.8 Embedding custom non-visible data with the data-* attributes
http://www.w3.org/TR/html5/elements.html#embedding-custom-non-visible-data-with-the-data-attributes

There is a note that reads:

--
All attributes on HTML elements in HTML documents get ASCII-lowercased
automatically, so the restriction on ASCII uppercase letters doesn't affect
such documents.
--

Later in the section there are several references to ASCII-lowercasing and
ASCII-uppercasing operations. There is no discussion of how to handle non-ASCII
Unicode values (the wisdom of any such appearing in this context is, of course,
open). Default Unicode case folding might be a good idea here, though, if such
values are expected to occur?
