The definition of [`x-sap-precision`](https://github.com/SAP/openapi-specification/tree/main/sap-schemas/v3.0#x-sap-precision) shows it use for a `DECFLOAT34` value in combination with `format:decimal`. However the [OpenAPI format registration for `decimal`](https://spec.openapis.org/registry/format/decimal.html) states that > The `decimal` format represents a **fixed** point decimal number of unspecified precision and range. Should we instead use the [newly registered OpenAPI format `decimal128`](https://spec.openapis.org/registry/format/decimal128.html) for `DECFLOAT34` values?
