 An attribute should have the following form:
 
 ```
-<attr_name>: {type: <type>, desc: <description>, required: <required>, properties: <another_hash> }
+<attr_name>: {type: <type>, desc: <description>, required: <required>, properties: <another_hash>, of: <another_hash> }
 ```
 
 - `attr_name` is the attribute name (sic)
 - `type` is the field type (check _entity definition_ for a list).
   `type` can be `:object` if the attribute contains other attributes.
 - `required` is optional an defaults to `false`.
 - `properties` is a hash of params and is only used if `type: :object`
+- `of` is a hash of params and is only used if `type: :array`
