We could set up a public attribute registry, like the one IANA maintains for media types:

We could even create a registry at IANA itself:

> The IPC profile and the EC-US profile both define an organization subject

> A conformant implementation or deployment supporting both profiles

> Furthermore, the EC-US profile says in section 5.1 that policies and requests
> "SHALL NOT use any other identifiers for the purposes defined by attributes

> the conformance criteria for the EC-US profile.
> I suggest that one of these profiles (I don't care which) defines the
> organization attribute and the other profile references that definition, or that
> both profiles define the attribute using the same identifier (and ideally,
> acknowledge that the other profile contains an identical definition).
