Ensure that the format keyword is valid for the type defined in the schema

Ensure that the format keyword is valid for the type defined in the schema. The format keyword is an optional modifier that allows for basic semantic validation on certain kinds of data. For example, the integer type can have the format of int32 or int64, and the number type can have the format of float or double. If the format is not valid for the type, it may cause errors or inconsistencies in the API behavior.
