CTypeValidator verifies if the attribute is of the type specified by type.

For date type, the property dateFormat will be used to determine how to parse the date string. If the given date value doesn't follow the format, the attribute is considered as invalid.
The following data types are supported:
- integer A 32-bit signed integer data type.
- float A double-precision floating point number data type.
