In Section 2:
'a. The code points must be from a space designated as "Specification
Required" (where an RFC will be used as the stable reference),
"RFC Required", "IETF Review", or "Standards Action".'
I suggest not having the comment (where) and leaving it to RFC 5226 to
define "Specification Required".
Yes, except that's not what this means.
I tripped over the same text, and I suggest rephrasing it this way:
NEW
The code points must be from a space designated as "Specification
Required" (in cases where an RFC will be used as the stable reference),
"RFC Required", "IETF Review", or "Standards Action".
