+I compared the following 7 approaches for labelling a close button:
+
+- K: Using `aria-label`.
+- L: Using `aria-label` and an explicit `lang` attribute.
+- M: Using `aria-labelledby` and referring to a visually hidden label outside the labelled element.
+- N: Using `aria-labelledby` and referring to a visually hidden and `aria-hidden` label outside the labelled element.
+- O: Using `aria-labelledby` and referring to a visually hidden label inside the labelled element.
+- P: Using `aria-labelledby` and referring to a visually hidden and `aria-hidden` label inside the labelled element.
+- Q: Using a visually hidden label inside the labelled element.
