    parent.addContent(new Element(STORE_SERIALIZATION_TYPE_ELMT).setText(def.getName()));
    if (def.hasSchemaInfo()) {
        for (Map.Entry<Integer, String> entry : def.getAllSchemaInfoVersions().entrySet()) {

            if (def.hasVersion())
                schemaElmt.setAttribute(STORE_VERSION_ATTR, Integer.toString(entry.getKey()));
            else
                schemaElmt.setAttribute(STORE_VERSION_ATTR, "none");
            schemaElmt.setText(entry.getValue());

        }
    }
