It's attribution _line_, not attribution novel.

There is nothing brilliant about it. This way you will have to put an ID
for the default radiobutton in each radiobutton group, that you must not
have used elsewhere, when you could have simply used the radiobutton group
name to refer to the first (or whatever) radiobutton of that *particular*
form, and you will have search for it by document.getElementById() in the
*whole* document. Even the `defaultValue' approach is smarter than that.

It is generally a bad idea to allow a user reset a form. They rarely need
it, and often do it accidentally, losing all their input.
Regardless, if you did the form well, reset() would have sufficed.
