 - Inside the crate you can use `cargo build` to build the library
     - Be sure to pass `--release` to get an optimized build
     - Specify Cargo features with `--features ...`:
+        - `compiled_data` to include data (`ICU4XDataProvider::create_compiled()`)
         - `buffer_provider` for working with blob data providers (`ICU4XDataProvider::create_from_byte_slice()`)
-        - `provider_test` to include testing data (`ICU4XDataProvider::create_test()`)
         - `provider_fs` for loading data from the file system (`ICU4XDataProvider::create_fs()`). This also requires enabling a syntax on the `icu_provider` crate.
         - `logging` and `simple_logger` enable basic stdout logging of error metadata. Further loggers can be added on request.
         - `cpp_default` turns on a bunch of these and is useful for exploration, but should not be used in production as it enables `provider_test`
