Here’s 3 ways to identify a profile. The first two are in EAT now. The last is not.

1) OID
2) URI
3) IANA first-come-first-served integer. No text strings, just a simple monotonic integer, 0, 1, 2, 3, 4… A URI can be associated with the integer if the profile is published, but it isn’t required.

We can do any combo of the above (e.g., what’s in the doc now, just 2 and 3,…). I don’t have a strong opinion, but just 3 seems in the spirit of being small and simple to me.

The two issues with 3) I can see are:
- Is it OK to consume more IANA resources here? I assume yes. It’s kind of their job and it isn’t hard to do this
- The profile was pre-allocated by IANA as OID and URI and there probably some implementations
