  "about": "The condition truth table of chapter 04. 'stored' is the record's value: {\"missing\": true} for an attribute the record doesn't have, {\"null\": true} for null. Values are typed: int, text, decimal (as text, exact), bool. Cases marked ignoreCase need case-insensitive text comparison (an implementation that can only compare with case, such as DynamoDB's, refuses those operators and skips these cases).",
