Yes, either (for any clist c):

 c = delete(c,wrong);

or

 bgp_community.delete(wrong);

But the second form works only for bgp_community attribute.
 
'wrong' should be declared as pair set, not as clist.

This code works for me.

This is a recent feature, perhaps you are using an old version of BIRD.
Try version 1.2.4 .
