a question about the data types here...
So, a neighbor with no downstream ASN could be filtered directly with
ROA == prefixlist-content.
A neighbor with a downstream ASN has to be ROA (per asn downstream) ==

So you'd now have to do some calculations which are more complicated
than just; "is roa for this prefix here and valid" to construct a
