Only external references are required.

However, to prevent other Members from accidentally making a property externally referenced, it is best to return null.

For example, some colleagues add a public method to your class to expose your private attributes and reference them... If you do not set null, the entire class cannot be destroyed ..

It seems that null is the safest choice.
