The ETSI OI ballot will probably come out in the next few days to a week.

Subject: [cabf_validation] Other Subject Attributes

We've recently had discussions about the meaning of EVGL section 9.2.8 in the 
context of adding Subject:organizationIdentifier for LEIs and the eIDAS/PSD2 
identifier. There is also uncertainty if the OU field is currently permitted 
to be included in EV certificates. I drafted a change that would clarify this 
by explicitly permitting OU and forbidding any Subject attributes not defined 
in the EVGLs, but I had been holding off on proposing this because I didn't 
want to do something that would conflict with any proposal from ETSI on 

Today there has been discussion on the Questions and Management lists about BR 
section and (j). Those sections suffer from a similar problem.

Here is a proposal to fix both issues: 

The intent is:

* Subject attributes other than those defined on the BRs are allowed in DV and 
OV certs, as long as the information is validated

* Metadata is prohibited in any Subject field in any type of cert

* For EV, OU is explicitly permitted, just like DV and OV

* For EV, only Subject fields that are explicitly defined are permitted

Any comments on this?

Would anyone like to endorse?

Do we need a future effective date for these changes? I believe they're 
already being enforced.
