I am curious as to how Pega knows the sections that are violating accessibility rules.  For example, it is able to detect that some properties on the screen may be missing a header, or Pega can tell if you need to add a helper text.  Is there a way to see the code that Pega uses?  Another link I found said that the Accessibility tool uses the same Javascript API as Live UI.  Is there a way to see that Javascript API that is being used?
