If there are multiple types allowed in `type` keyword the coercion will only happen if none of the types match the data and some of the scalar types are present (coercion to/from `object`/`array` is not possible). In this case the validating function will try coercing the data to each type in order until some of them succeeds.
If `coerceTypes` is set to `array`
Possible type coercions:
