Overview

Defines attribute names to be set in a Model class. This allows pre-defining a set of attributes to be set at once in a Model without having to declare each one by hand.

A Schema is a loose concept. This is just a convenience class to be used when a more robust object is not present. In reality, any object that responds to ‘attribute_names` can be used as a Schema.
