#7 Email addresses in contacts

FIRS seems to require a contact to have their email address in the DN.

 From draft-ietf-crips-firs-contact-02:

>      The inetContactSyntax is unstructured, in that it uses 
>      standardized procedures to produce heavily-normalized email 
>      addresses rather than using structured syntax rules. The principle

This means that in order to reference the contact, a referral or 
reference to the contact must expose the email address of the contact. 
I think this has privacy implications all over it.

I assume this is the same escaped Unicode as discussed earlier?  Correct?

Why do email addresses have to be handled differently?  I thought one of 
the points of IDN was that we wouldn't have to change things like email 
addresses?  Not being an IDN person, I could have this all screwed up.

Is the point that the email addresses cannot be the xn-- versions and 
must be Unicode?
