Just a heads up I think most of us would agree that the event method
is the last place we put validation. I truly expect that all input
data is valid by the time it gets to an event handler.
Here is my preferred order
Field Level @Validate or @ValidateNestedProperties
Method @ValidationMethod
Finally if there is no other way custom validation code in the event handler.
My 2 cents
