version property
Version is the exact baseline version consulted, composed of each contributing publisher and its content digest. It is what makes a decision reproducible: an auditor takes this string and knows precisely what was consulted.
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? version;
