As the path of each *path operation* has to start with `/`, like in:

```Python hl_lines="1"
@router.get("/{item_id}")
async def read_item(item_id: str):
    ...
```

...the prefix must not include a final `/`.

So, the prefix in this case is `/items`.

We can also add a list of `tags` and extra `responses` that will be applied to all the *path operations* included in this router.

        <ExcludedPrefixes>
          <Prefix>*/_temporary</Prefix>
        </ExcludedPrefixes>

          <Prefix>*/__magic</Prefix>

        <ExcludedPrefixes>
