The _type_ may be `string`, `float`, `int`, or `bool`.
If the type is `bool`, then original attributes of `0`, `false`, `null`, or the empty string become `false`, and otherwise become `true`.
If the type is `bool`, then original attributes of `0` (or, if numeric, `0.0`, etc.), `false`, `null`, or the empty string become `false`, and otherwise become `true`.
If the type is `float` or `int` and the original attribute was non-numeric, it becomes `0`.
If the type is `int` and the original attribute was floating-point, it is rounded to the nearest integer.
