So when are you releasing the BGP5s draft?
And should I also expect to see the BGP5m, BGP5a etc drafts?
This is sounding like propritary protocols to me.

There seems to be a disconnect here.  Adminstrative / Organizational
are two different things as you have stated elsewhere in this thread.
I agree that a one-to-one corelation between organization & AS is 
a rare creature.  I will continue to preach that there is a one-to-one
corelation between an administrative domain and an AS.

I have seen no proof that it does not conform to my view of what an
AS is.  What I see is an attempt to turn a screw into a nail. (as in
when all you have is a hammer)

The RADB reflects the policies of those registering... as long as
it is expressible in RIPE-181 syntax.  Since there are some problems
doing that, there may be proposed changes to RIPE-181 in the future 
so that more complex policies can be registered.  This portion of the
thread is tangental to AS creation and ASN assignment.
