If _completely_hidden_ is the requirement, then I agree that any
option that is no f(x) = 1 (for fixed values of 1) fails.

Why have the long string "(PRIVATE)" at all then?  Would a single '?'
not be adequate?  I don't think you will ever find '?' in a real
dNSName.
On a related note, is there any plan to support blinding other general
name options?  Can email addresses in rfc822Name or ipAddresses be
blinded?

Thanks,
Peter
