Response from the Working Group
================================
Because the errors in your example are identified and described to the
user in text, it sounds as though what you describe would pass.
However, best practice would be to also include a message or alert as
some users may not be aware that an error has occurred and could
assume that the form is not functioning correctly.

It is also best practice to include an error notification in the page
title (title element) since a screen reader user is likely to believe
the page was submitted correctly and continue to navigate to another
page as soon as the new page is returned instead of reading the main
content area of the page again. We will add an advisory technique and
a note that describes this.
