formatSet
formatSet: string | undefined
Identifier of a FormatSet whose formats take precedence for this field, letting one iModel mix presentations such as metric and imperial callouts.
Application-chosen, and matched against the ids supplied to ElementDrivesTextAnnotation.registerFieldFormatting; iTwin.js does not resolve it against anything persisted in the iModel. A field naming an id that was never supplied resolves as if it named none: through the iModel's adopted FormatSet, then the schema presentation format.
