Re: [sidr] New Version Notification for draft-ymbk-sidr-transfer-00.txt

As Arturo mentions, defining 'actual use' of number resources has proved
quite tricky.

The only workable assumption is that space that is marked 'available' or
'reserved' in the delegated-extended files is not in use whereas
everything else is in use, regardless of whether it is announced in the
Internet or not.

Even this assumption could lead to unexpected situations here and there
as there could be space being recovered that is still routed in bgp
while being marked as reserved, not mentioning possible ongoing route
hijacks of 'available' space still getting traffic.

cheers!
