I can see that the OData validation assertion supports up to OData 2.0. My guess is that I can still consume an OData 4.0 request for as long as I bypass the validation. Understand that I could incorporate some custom assertions to add some level of validation but may not be as inclusive as a proper assertion for OData 4.0. So, I will like to confirm if my assumption is correct regarding consuming an OData 4.0 without the validation assertion. I will also like to know if there is any plan to provide support for OData 4.0 validation assertion in the future.
