OK.  Note that

1)  The tests in 
https://github.com/w3c/web-platform-tests/tree/master/selectors/attribute-selectors/attribute-case 
agree with Blink here, and weren't even contributed by a Blink developer.

2)  I'm aware of the general case-insensitivity of CSS, and it still 
wasn't clear to me what the spec was trying to say, especially given the 
existing implementations and the tests.

So I still maintain that an example using 'I' would be a good idea, just 
to get everyone on the same page.
