The specification document at [CSL 1.0.2 Specification — Citation Style Language 1.0.1-dev documentation](https://docs.citationstyles.org/en/stable/specification.html#number-variables) uses `part-number` but the schema at [schema/csl-data.json at master · citation-style-language/schema · GitHub](https://github.com/citation-style-language/schema/blob/master/schemas/input/csl-data.json) still has `part`. Same for `supplement(-number` etc. Which is the current one?
