    * @param {string}                  [attributes.column.onDelete] What should happen when the referenced key is deleted. One of CASCADE, RESTRICT, SET DEFAULT, SET NULL or NO ACTION
    * @param {Function}                [attributes.column.get] Provide a custom getter for this column. Use `this.getDataValue(String)` to manipulate the underlying values.
    * @param {Function}                [attributes.column.set] Provide a custom setter for this column. Use `this.setDataValue(String, Value)` to manipulate the underlying values.
-   * @param {Object}                  [attributes.validate] An object of validations to execute for this column every time the model is saved. Can be either the name of a validation provided by validator.js, a validation function provided by extending validator.js (see the `DAOValidator` property for more details), or a custom validation function. Custom validation functions are called with the value of the field, and can possibly take a second callback argument, to signal that they are asynchronous. If the validator is sync, it should throw in the case of a failed validation, it it is async, the callback should be called with the error text.
