Careful with this, e.g. AS-NULL. There are some situations where referencing an empty set can be useful in RPSL.

I'm not sure whether Nick meant this as a single exception, or rather as an example of a category of useful empty sets. I can well imagine that most "operationally empty objects" (as Denis put it) are either useless or troublesome. As Nick says, "Careful with this." Niall
