This layer performs the following tasks: - validation of structures; structures are recursed if necessary - validation of enumerated type values - null pointer conditions - stateless valid usage checks - checks requiring only static state such as properties or limits The Stateless Validation is run before [Core Validation Checks](core_checks.md). If there is a validation error found in Stateless Validation, it will return and not call Core Validation nor call down the layer chain.
