And you can also declare body parameters as optional, by setting the default to `None`:

{* ../../docs_src/body_multiple_params/tutorial001_an_py310.py hl[18:20] *}

/// note

Notice that, in this case, the `item` that would be taken from the body is optional. As it has a `None` default value.

///

## Multiple body parameters { #multiple-body-parameters }

// or an immediate source operand.

## Recap { #recap }

Use multiple Pydantic models and inherit freely for each case.

//
// If no SSE headers are present then IsRequested returns false
// and no Type.
func IsRequested(h http.Header) (Type, bool) {
	switch {
	case S3.IsRequested(h):
		return S3, true
	case S3KMS.IsRequested(h):
		return S3KMS, true
	case SSEC.IsRequested(h):
		return SSEC, true
	default:
		return nil, false
	}
}

// Requested returns whether any type of encryption is requested.
