The current documentation states that the `<select>` tag supports `defaultChecked`, but it actually doesn't. I believe this documentation was meant to be written in the proposed order.
Non-working fiddle using `defaultChecked`: http://jsfiddle.net/jqs1hsLr/1/
Working fiddle using `defaultValue`: http://jsfiddle.net/nv7z0yzL/1/
This will let us keep docs in order on the filesystem but have
reasonable permalinks. If we add something at 02- it doesn't result in
lots of broken links.
