hi jakob,

i am confused between

> There is no expansion to prefix-set.

and your earlier

>> We have introduced the scalable as-set into the XR route policy language.
>> as-path-set does not scale well with 1000's of ASNs.
>> Now, you don't need to expand AS-SET into prefix-set, just enter it directly.

expanding AS-SET into prefix filters is exactly what we do.

```
% peval -s RIPE AS-RG-SEA
({198.180.153.0/24, 198.180.151.0/24, 147.28.8.0/24, 147.28.9.0/24, 147.28.10.0/24, 147.28.11.0/24, 147.28.12.0/24, 147.28.13.0/24, 147.28.14.0/24, 147.28.15.0/24, 147.28.4.0/24, 147.28.5.0/24, 147.28.6.0/24, 147.28.7.0/24, 147.28.2.0/24, 147.28.3.0/24, 147.28.0.0/23, 45.132.188.0/24, 45.132.189.0/24, 45.132.190.0/24, 45.132.191.0/24})
