// There are jtreg tests checking the _features_string for various properties.
// For some strange reason, these tests require the string to contain
// only _lowercase_ characters. Keep that in mind when being surprised
// about the unusual notation of features - and when adding new ones.
// Features may have one comma at the end.
// Furthermore, use one, and only one, separator space between features.
// Multiple spaces are considered separate tokens, messing up everything.
