Hi Dermot,

Don't worry - this isn't a silly question at all!

As Moritz said, checked="checked" is equivalent to the old `checked`,
and should work just fine in HTML4 - it's just that our output is
geared towards being valid xhtml.

I think there's a more "correct" way of doing this, though.
You should always be setting the Checkbox's value(), so that the
browser knows what to send back when it's checked.
In this case, you could just do this

    $box->default( $c->model->{val} );

And the Checkbox is smart enough to set checked="checked" when
default() is the same as value().
And if they're different, the default() will just be ignored.
