In particular, CSS says that whether [foo=bar] matches <div foo="BAR"> is defined by the document language.

Note that UAs may not be all that consistent here.  What Gecko does is case-sensitive matching except for a whitelist of attributes whose values are explicitly defined as case-insensitive in HTML4, I believe.  See http://hg.mozilla.org/mozilla-central/file/f60b87eed1ac/layout/style/nsCSSParser.cpp#l3338

Is this insufficient?:

Comment 3 Boris Zbarsky 2013-01-10 22:44:33 UTC 
Hmm.  I totally failed to find that for some reason, even after searching the single-page version of the spec for "Selector"....

If there's anything I can do to make that more discoverable, please don't hesitate to file a new bug (or reopen this one).
