Initially,  section 4 was 'simple mode' and was renamed 'non 
authenticated mode' by reference
to the fact that no specific authentication was required.
This is a left over from that time, thank you for pointing it.

Since then, others made the comment that is this mode is restricted to 
the IPv4 ISP customers,
there is already some kind of authentication in place at the IPv4 
layer, thus calling this
'non authenticated' is a bit of a misnomer...

Any suggestion for a alternate name would be welcome.

Actually, this raises another point. Are both modes (authenticated and 
non-authenticated) necessary?
Will ISPs be willing to deploy such tunnels in the mode described in 
section 4. especially
in light of the security considerations discussed in section 4.4?

Any feedback on this topic from operational ISP people would be greatly 
appreciated.
