transactionId property
The transactionId is used when a single service had to be split into parts for technical reasons. Several services with the same non null transaction id form one single service
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? transactionId;
