    """Enable translated validation error messages.

    Makes sure that when a user submits invalid data (for example, a
    required field is missing), the error message shown to them is
    translated into their chosen language instead of always being shown
    in English. Takes no parameters; call it once, near the top of
    ``invenio.cfg``.

    Invenio configuration variables set: none - this only patches
    Marshmallow's error-message machinery in memory.

    Example:

    .. code-block:: python

        config.initialize_i18n()
