    The summary is that it ignores one file in favor of the other.
    util.concurrent, like nearly all our packages, has two .gwt.xml files: one
    for prod and one for tests. However, unlike our other packages, as of this
    writing it has test supersource but no prod supersource.

To declare types that have type parameters (internal types), like `list`, `dict`, `tuple`,
pass the internal type(s) as "type parameters" using square brackets: `[` and `]`

```Python
my_list: list[str]
```

That's all standard Python syntax for type declarations.

Use that same standard syntax for model attributes with internal types.

So, in our example, we can make `tags` be specifically a "list of strings":
