I came across an issue on a React project where I needed to programatically set the default value of an input as the result of an async call. (I was prepopulating a zip code field from the Google Maps Geocoding API). It didn't work when I passed in an updated defaultValue prop, until I came across this StackOverflow: http://stackoverflow.com/questions/30146105/react-input-defaultvalue-doesnt-update-with-state. I was able to get it to do what I wanted by passing in the value prop instead.
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.

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.
