The range validations add a very large amount of complexity. I'm starting to think about how much we really need them. Sure length validation for article descriptions might be good, but do we really need to validate date ranges and integer values? Maybe it would be better to allow arbitrary Laravel validation rules to be specified in the schema file instead of its min/max values.
