refusal property
Refusal is why this publisher's last take failed, if it did. The set keeps its previous version of this source and ages out visibly rather than silently shrinking.
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? refusal;
