    "description": "Checks if **any** (i.e. at least one) value in `data` is `true`. If no value is given (i.e. the array is empty) the process returns `null`.\n\nBy default all no-data values are ignored so that the process returns `null` if all values are no-data, `true` if at least one value is true and `false` otherwise. Setting the `ignore_nodata` flag to `false` takes no-data values into account and the array values are reduced pairwise according to the following truth table:\n\n```\n      || null | false | true\n----- || ---- | ----- | ----\nnull  || null | null  | true\nfalse || null | false | true\ntrue  || true | true  | true\n```\n\n**Remark:** The process evaluates all values from the first to the last element and stops once the outcome is unambiguous. A result is ambiguous unless a value is `true`.",
