Your response model could have default values, like:

{* ../../docs_src/response_model/tutorial004_py310.py hl[9,11:12] *}

* `description: Union[str, None] = None` (or `str | None = None` in Python 3.10) has a default of `None`.
* `tax: float = 10.5` has a default of `10.5`.
* `tags: List[str] = []` has a default of an empty list: `[]`.

          <description>The default goal to execute when none is specified for
            the project. Note that in case of a build with subprojects, only the default goal of the top-level
            project is relevant, i.e. the default goals of subprojects are ignored. Since Maven 3,
            multiple goals/phases can be separated by whitespace.</description>
