@Override

Returns a collection of model objects which mirrors the contents of this
ArbitraryAttributeMap. Each name/value pair within the map is reflected
by a corresponding model object within the returned collection. Removing
a model object from the collection removes the corresponding name/value
pair from the map. Adding a new model object to the collection adds a
corresponding name/value pair to the map. Changes to a model object
within the collection are NOT reflected on the map, however.

@return
    A collection of model objects which mirrors the contents of this
    ArbitraryAttributeMap.
