- Morphology: lemon does not provide process descriptions of inflection generation.
- Lexeme properties in subcategorization frames: this is replaced by MWE/Frame links
- Synsets: lemon handles this through the use of ontology reference, i.e., the synset is the set of lexical senses that share a reference.
- Tests of cross-lingual mappings: replaced by sense conditions
- Global lexicon constraints: replaced by OWL restrictions
