changes property
Changes is how many DISTINCT regimes may be adopted per Window. A restatement identical to the regime in force mints no version and is not counted against it.
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.
