It seems like $parent of type object<nstdio\svg\ElementInterface> is incompatible with the declared type object<nstdio\svg\XMLDocumentInterface> of property $root.

        $this->element = $this->createElement($this->getName());

The call to XMLDocumentInterface::createElement() has too many arguments starting with $attributes.
