jquery.validate multipage demo not accessible for screen readers.

It seems that the multi-page demo removes all screenreader cues. It seems to use the label tag incorrectly and there is no 'required' added to the input field.

Can the multi-page demo be easily updated to be accessible to screen readers?

The non multi-page demo seems better except that it removes the default browser functionality that displays an error as the user moves away from a particular field.
