We're using extras on stage 3.  Sean fixed this a better way in
release-v2.0, but I see we're still running with my old patch, so try
it and see if it makes a difference (it shouldn't):

Other than that you can look at our schema, but be warned, it is
pretty complicated.

The result is that extras on stage 3 have validators like:
[ignore_missing, unicode, convert_to_extras]
