I think you need to also add: "and cannot easily obtain one". My
understanding is that they are easy to obtain. See
http://www.iana.org/assignments/enterprise-numbers. There is also an
online application form on the IANA page.

I can live with this.

The VUID-DN definition says the DNS name is in ascii.
