The problem is most likely the one described here:
https://www.eclipse.org/forums/index.php/t/367763/

As far as I understood it, the parser in the current code tries to serialize an empty element.
Usually the element is created implicitly on the first access to a member . But since there is no such elements, the EMF object itself is also not created.
Adding
{Element}
will explicitly create the EMF object at the beginning of serializing the rule and therefore it is then present and the serializer is happy :).
