Hi Job and all,

Do we need a statement in the profile document to make it clear what AFIs the ASPA profile specification applies to? Should we make it clear that it does not apply to AFIs other than 1 and 2? 

Suggestion for the wording:

---
The specification of the ASPA profile in this document is applicable only to address families IPv4 (AFI = 1) and IPv6 (AFI = 2). The Set of Provider ASes (SPAS) listed in the ASPA is considered applicable to both AFI = 1 and AFI =2. In rare cases, if a CAS considers some transit providers to be unique to one address family, it MUST still list the union of all transit providers applicable to AFI = 1 and AFI =2 in the SPAS.
---

An alternative is to say nothing about the AFI in the profile document (as currently the case with v-15). Instead, state the above (with somewhat different wording) only in the ASPA verification document?

Thank you.

Sriram
