- L-attributed grammar : inherited attributes can be evaluated in top-down parsing.
- LR-attributed grammar : an L-attributed grammar whose inherited attributes can also be evaluated in bottom-up parsing.
- ECLR-attributed grammar : equivalent classes can also be used to optimize the evaluation of inherited attributes.
