module PhModel::Concerns::AttributeTypeValidation
This will validate any attribute defined with `type: ` the type value should be a class, or the special notation `[SomeClass]` which is meant to designate that this is a collection of those classes
`no_type_check: true` can be optionally passed to disable this check (other features might use the `type` column)
