source_ property
Source is the asserter these two counts are for — chargeoff, dispute, case, refund, review or sample. There is one entry per source that either filed in the window or won in it, in precedence order, strongest first. A source no longer in the vocabulary still has rows and is reported after the known ones rather than dropped out of a total that is supposed to add up.
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.
