I'm inclined to say an aria-label attribute value that consists of
nothing by white space is "empty". Given that, rule 2C could be
clarified as: "... if the current node has an aria-label attribute
whose value is not the empty string and does not consist only of white
space ..."
You could also phrase it to trim (better yet, normalize all whitespace and then trim) before checking the values. I'm happy with either edit.
