I agree with this.

Subject: [arin-ppml] Origin AS Semantics

An interesting question came up on Tuesday in the ARIN IRR Roadmap at NANOG.  
Essentially, what is the intended semantics of Origin AS? See timestamp 20:14 
to 21:04 in the following video;

https://youtu.be/tsWq_LgNS5s

Some background; Section 3.5 of the NRPM, originally Policy ARIN-2006-3, 
specifies the creation of what is now the "Origin AS" field in ARIN's registry, 
see;

https://www.arin.net/policy/nrpm.html#three5
https://www.arin.net/policy/proposals/2006_3.html

So back to the question; "are you allow to announce any more specifics based on 
the Origin AS?"

Note the last sentence of section 3.5.1 says the following;
This additional field will be used to record a list of the ASes that the user 
permits to originate address prefixes within the address block.

While the policy doesn't formally specify the semantics for this field, based 
on the above sentence, I personally have to conclude that the policy intends 
that more specifics should be permitted based on the "Origin AS" filed.

Does anyone read this differently?

Do we need to further clarify this in the policy?

Thanks.

Seems pretty explicit to me.

“…list of the Ages that the user permits to originate address prefixes within 
the address block.”

So far, I’ve been unable to imagine any interpretation of “within the address 
block” which would exclude more specifics.
