Do not know if radio buttons and checkboxes should be required to have a non-empty value.
Comment 1 Alan Jenkins 2012-09-14 12:44:13 CEST
Checkboxes in forms work without a value (it just won't make much sense if you have more than one with the same name and no value).  I tested it in Firefox 15.

I don't see such a _requirement_ anywhere.  You're allowed to use inputs outside of forms.  In that case you could identify them by id only - and it would probably be most convenient to do so.

Radio buttons in forms - maybe as a warning.

You're not allowed to have a radio button with a name attribute on its own; there MUST be at least two with the same name.  You could check that first - then warn if the values are not all unique[1].  The empty value is not a special case in that respect.

Another warning could be for radio buttons with no name.  (Radio buttons which don't belong to a radio group are pretty pointless).

[1] <> "A document must not contain an input element whose radio button group contains only that element".
