whois query for as-set object

Hi,

a problem again ;-(

http://www.ripe.net/ripencc/pub-services/db/rpsl/queries.pdf says:

 Function               | RIPE DB v3.0
 ------------------------------------------
 Get full as-set object | -r -Tas AS-######

but this doesn't work with hierarchical set-classes like AS1270:AS-UUNETDE

whois -h rpsl.ripe.net -p 4343 -r -T as-set AS1270:AS-UUNETDE
%ERROR:101: no entries found

whois -h rpsl.ripe.net -p 4343 -r -T as-set -i mnt-by uunetde-mnt

as-set:     AS1270:AS-UUNETDE
descr:      UUNET/DE
