holder property
Holder overrides who the token is issued to; defaults to the caller's own validated subject. It NAMES the token's bearer and grants nothing on its own — the entitlement checked is always the caller's org's.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
String? holder;
