A collection containing the data items used to populate the parent.

This property can not be used together with Count.

The provided object must implement IArray. To support dynamic changes to the collection, it can also implement IObservableArray. For example, if a FuseJS/Observable is provided, this implements IObservableArray.

Each item in the collection can in turn be an IObservable. If so, the Each will subscribe to these items and use the dynamic value. However, this will not work in combination with the MatchKey, IdentityKey and MatchObject features which require an immediate value.

For legacy reasons, this property will also accept an object[] as the collection. This feature is deprecated.
