Fixed version (ground truth):

      final ModelNode contentItem=modelNode.get(uniqueName);
      writer.writeStartElement(Element.DEPLOYMENT_OVERLAY.getLocalName());
      writeAttribute(writer,Attribute.NAME,uniqueName);
      if (contentItem.hasDefined(CONTENT)) {
        final ModelNode overridesNode=contentItem.get(CONTENT);
        final Set<String> overrides=overridesNode.keys();
        for (        final String override : overrides) {

        }
