It seems like $this->type can also be of type null; however, parameter $sClass of Jaxon\App\Metadata\Data\ContainerData::addValue() does only seem to accept string, maybe add an additional type check?

It seems like $this->attr can also be of type null; however, parameter $sAttr of Jaxon\App\Metadata\Data\ContainerData::addValue() does only seem to accept string, maybe add an additional type check?
