When a submitted form contains errors and re-appears to the user
together with the error messages, I need some way to co-relate each
error message with a text field. For this, I had thought of using the
aria-describedby property. Am I wrong? I read somewhere that I could do
that. if I don't use this aria attribute, as you say that I don't have
to, then how am I going to relate the error message to the field, so
that my user will know?

Do aria-* attributes apply to websites that don't have any AJAX?

Thanks,
