Have you tried looking in the Fontconfig source?

On the contrary, Fontconfig’s config parser does everything we need it
to do: accept exactly that set of valid config files and reject
everything else. And it doesn’t just provide syntactic validation, but
also semantic validation as well: we can use it to test that the config
does in fact do what we expected it to do.
