 #### Failed Example 15
 
-This rule has no special handling for digits that appear next to letters with no spaces in between.
+The [label in name algorithm][] works on full words.  That is: it requires that each full word in the visible label ("1" in this case) is equal to a full word in the accessible name ("1a" in this case).  Those two words - "1" and "1a" - are not equal, so this element fails the rule.
