Summary: Ready with questions.

The language is quite clear and precise.  I did find that
comprehension required a non-trivial amount of digging into other
documents, but nothing was particularly hard to find.

This has a downref to 6507 (I see this in the shepherd writeup).

Questions:
The security considerations notes that the trusted authority has
access to private keys.  That would seem to defeat much of the benefit
of using asymmetric crypto here.  Why is this considered acceptable in
this context?  (I'd have thought it to be unacceptable in any context
when superior alternatives exist.)

The document mentions revocation, but does not seem to specify
anything.  If that is intentional, shouldn't the draft be more forward
about that?  (I only skimmed 6507 and the other docs, so I apologize
if I missed something.

Nits:
S4.1: duplicate "in in"

S5: It's probably not necessary to amend the reserved codepoints in
the registry: that rots quickly.
