The description of the Strict Type Checking property for the ValidateRecord processor states:
If false, the Record will be considered valid and the field will be coerced into the correct type (if possible, according to the type coercion supported by the Record Writer).
In my testing I've confirmed that in this scenario, the records are considered valid. But, none of the record fields are coerced into the correct type.
We should either correct the documentation or implement the promised coercion functionality.
