Hi there,

Definitive responses should come from Ron, but in the interest of moving things 
along, here are my thoughts...

No, I don't think this is an aside. It is a "Nota Bene" type of "NOTE", not to 
be glossed over by the reader.

The pedant in me (which will not die!) says that we don't do experimentation in 
the registry :-Z
But, if you, as a native speaker, find this clearer, I don't object.

I prefer this second formulation (with the two pieces of introductory text)

I see only one "IPv6 VPN Service option" [sic] which is in Section 7.
Thus, please change that to "VPN Service Option".

But there is also "IPv6 VPN Service Destination Option"

The document title should remain as it is (qualifying the VPN Service Option to 
IPv6).
The other cases (Sections 5 and 7) can all change to "VPN Service Option".

> Destination Options header
> IPv6 Destination Options Extension Header

I only found one " IPv6 Destination Options Extension Header" (in Section 4).
It serves as a sub-heading and contrasts with "IPv6 header" above the previous 
bullets, so I think it is good.
On the other hand, please s/IPv6 header/IPv6 Header/ in that previous 
sub-header.

Correct as written in the original.

This overlaps with part of point a).
I believe it is fully covered there, but please come back if it is unclear.

Would ideally be "VPN Service Destination Option", but if that is too long, 
"VPN Service Option".

All fine, but really is time to make these three "well known" :-)

I looked again, and found nothing of concern.

No! Thank you.
