Implementation of the handler interface

// PetPost creates a pet.
// POST /pet
func (h *Handler) PetPost(_ context.Context, req rest.PetPostReq) (*rest.PetPostOK, error) {
	var data rest.Pet

	switch v := req.(type) {
	case *rest.PetPostApplicationJSON:
		data = rest.Pet(*v)
	case *rest.PetPostApplicationXWwwFormUrlencoded:
		data = rest.Pet(*v)
	}
	return &rest.PetPostOK{
		ID:       rest.NewOptInt(data.ID),
		Name:     data.Name,
		IsActive: data.IsActive,
	}, nil
}

Content type application/json

 curl -X POST "127.0.0.1:8080/pet" \
     -H "Content-Type: application/json" \
     -d '{"id":1}' 
{"id":1,"name":"DefaultName","isActive":true}

Content type application/x-www-form-urlencoded

 curl -X POST "127.0.0.1:8080/pet" \
     -H "Content-Type: application/x-www-form-urlencoded" \
     -d "id=1"
{"id":1}

Expected behavior

When sending a request with either application/json or application/x-www-form-urlencoded content type, the default values specified in the schema should be automatically applied if the corresponding fields are missing in the request.

Observed behavior

The default values are correctly applied for application/json, but they are not applied when using application/x-www-form-urlencoded.
