Hi Jakob,

IMHO we should learn form the past (read: MED experience) and when 
allowing for a given cost community to be transitive across ASes it's 
definition should very clearly indicate that in the event of using 
potentially different ranges of values they must be normalized to be 
able to be comparable in each AS they are transmitted to without 
necessity of any additional grouping.

Cheers,
R.
