So, you could add additional data to the automatically generated schema.

For example, you could decide to read and validate the request with your own code, without using the automatic features of FastAPI with Pydantic, but you could still want to define the request in the OpenAPI schema.

You could do that with `openapi_extra`:

```Python hl_lines="19-36  39-40"

        Set<String> roleSet = new HashSet<>();
        roleQueryHelperImpl.processParameter(request, roleSet);
        return roleSet;
    }

    private Set<String> buildByHeader(final RoleQueryHelper roleQueryHelperImpl, final HttpServletRequest request) {
        Set<String> roleSet = new HashSet<>();
        roleQueryHelperImpl.processHeader(request, roleSet);
        return roleSet;
    }

		date    time.Time
		region  string
		service string
		request string
	}
}

// Return scope string.
func (c credentialHeader) getScope() string {
	return strings.Join([]string{
		c.scope.date.Format(yyyymmdd),
		c.scope.region,
		c.scope.service,
		c.scope.request,
	}, SlashSeparator)
}
