[css-values] Case sensitivity of attr()

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

"The case-sensitivity of attribute names depends on the document language."


No text about the case sensitivity that I can find. I suppose it should  
have something similar to CSS2 or  

Anne van Kesteren suggests:

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...
