Wasn't this ambiguity already solved by introduction of hierarchical AS-SET?
That was also a good addition, but does not solve this problem. Keys are still not unique among all IRRs. Not all do (or can) validate against an aut-num's maintainer. Hierarchical AS-sets also do not allow graceful upgrades, i.e. you need everyone who uses your as-set to update the reference if you change from AS-EXAMPLE to AS64500:AS-EXAMPLE, and have two in the mean time. There is no enforcement of their consistency during this time. It might be useful for me and James to gather some specific numbers on all this, but that will take a bit of time. Sasha
