Response from the Working Group
Thank you for your comment.  The technique as it stands is still
sufficient, regardless of the number of times it is applied, because if it
is correctly applied for every form field, the success criterion will be
satisfied, no matter how many form fields there are.

Note that in the example, the field is validated as soon as it is
completed. It is not necessary to submit the form to validate the field.
However, missing required fields may not be caught until the form is
