Hi Jeff,

IDR has a rule to progress any doc which demonstrates two implementations.
That means that each draft which requires new BGP attribute and is accepted
as an IDR WG doc should get IANA code point such that implementations could
be delivered without risking any further inter-operability or deployment
issues.

Not sure how long WG should wait before such code point is depreciated
though ... but without it being allocated in some way it is going to always
be a challenge.

/RR.
