John, these are great additions, but please be advised that in some
browsers this.attr('checked', 'checked') won't work as expected. I
suggest that way (unless the fix is already done in attr which I don't
quite remember right now):
if ( b )
this.checked = true;
else
this.checked = false;
I think if you want to completely remove the attribute you can use
removeAttr but that has to be distinguished from setting the value to false.
