    if (paramListElem->ValueStr().compare("paramlist") != 0) {
        SYNTAX_ERROR(paramListElem->Row()) << "Expected \"paramlist\". Found" << paramListElem->ValueStr();
    }

    ParamList params;
    Param mainparam;

    if (paramListElem->QueryStringAttribute("name", &mainparam.name()) != TIXML_SUCCESS) {
        SYNTAX_ERROR(paramListElem->Row()) << "\"paramlist\" element should contain the \"name\" attribute";
    }

    params.push_back(mainparam);

    // yDebug() << "Found paramlist [" << params.at(0).name() << "]";

        params.at(0).value() += (params.at(0).value().empty() ? "(" : " ") + param.name();
    }
