Please see https://github.com/whatwg/html/issues/991

CSS2:
"The case-sensitivity of attribute names depends on the document language."
https://drafts.csswg.org/css2/generate.html#propdef-content

css-values:
https://drafts.csswg.org/css-values-3/#funcdef-attr

No text about the case sensitivity that I can find. I suppose it should  
have something similar to CSS2 or  
https://drafts.csswg.org/selectors-4/#case-sensitive


Anne van Kesteren suggests:

> those to be defined on "document" or wherever) to make this more  
> explicit. Would attr() ever be different from attribute selector

For now I suppose we can add attr() in HTML (with the same rules as  
attribute selectors) but we can investigate better ways of handling this,  
in particular if CSS will add new features that should have these rules...
