// The value returned in D8 would be LANGUAGE_NONE, we cannot use it here to
// preserve backward compatibility. In fact this function has been
// introduced very late in the D7 life cycle, mainly as the proper default
// for field_attach_form(). By returning LANGUAGE_NONE when no language
// information is available, we would introduce a potentially BC-breaking
// API change, since field_attach_form() defaults to the default language
// instead of LANGUAGE_NONE. Moreover this allows us to distinguish between
// entities that have no language specified from ones that do not have
// language support at all.
