OK

- ProcedureParameterVersionPaginatedList
  - `items` ProcedureParameterVersion[]
    - `__typename` string
    - `allowedEquipmentModels` ProcedureParameterVersionAllowedEquipmentModels
    - `amountDataType` ProcedureParameterDataType: Specifies the value type configuration for a procedure parameter. Used within `ProcedureParameterVersion` to define what kind of data a parameter accepts. The `type` field indicates the field type (such as text, decimal, entity link, or dropdown). For numeric types, `unit` optionally references a `Unit` for measurement context. For entity link types, `schema` optionally constrains values to entities of a specific `EntitySchema`. Also used as `amountDataType` on material input parameter versions to define how amounts are specified.
