This is the case for SVG classes, too, but maybe it's up to the SVG spec  
to define that.

Why are values case-insensitive only in HTML documents? The values are  
case-insensitive in XHTML, too.

Add a class to make the list more compact.

This list is missing charset and ismap, and presumably the new attributes  
in HTML5:

xml:lang (in no namespace) seems to be case-insensitive (although we might  
want to skip this one).

scoped
async
reversed
seamless
autobuffer
autoplay
loop
controls
autocomplete
novalidate
autofocus
formenctype
formmethod
formnovalidate
formtarget
required
wrap
keytype
open
hidden
contenteditable
draggable

...and maybe from the obsolete elements section:

behavior
direction
truespeed
