T1B: Static Semantics
- The paper’s main contribution concerns static semantics, especially typing or constraint checking.
T4A: Workbenches
- It includes substantial tool support or infrastructure relevant for engineering/using languages.
T5D: Formal Methods
- It relies on formal methods (definitions/proofs/semantic properties) beyond informal description.
T4C: Vertical Transformation
- It uses compilation/generation/refinement to derive executable artefacts (vertical transformations).
