There seems to be a discrepancy concerning this feature: Case does not appear in the GENELEX and AlethDic models amongst the features for Nouns, owing to their monolingual French-based orientation.

The relationship between the values, as far as it can be derived from their use in the analysed tagsets, is illustrated in the following tree:
It must be stressed that each language system will use its own pertinent set of values.
Oblique, discussed here as a value of the feature Case, is not pertinent to the category Noun; it is a value marked for Pronouns.
