"3.  Definition of IPv6-only

   Consequently, considering the context described in the section above,
   if we want to be precise and avoid confusing others, we can not use	
   the terminology "IPv6-only" in a generic way, and we need to define
   what part of the network we are referring to.

   From that perspective, we define the "IPv6-only" status in a given
   part(s) of a network, depending on if there is actual native
   forwarding of IPv4, so IPv4 is not configured neither managed."

The document defines IPv6-only not only for the network parts but also for a host/router.

"7.  IPv6-only WAN/access

   IPv6-only WAN or access can be used only if the WAN or access network
   isn't actually natively forwarding IPv4."

Should use affirmative kind of definitions for IPv6-only, not only here but also in other sections. Instead of "isn't actually natively forwarding IPv4" should define what it IS forwarding, like "is natively forwarding IPv6".

"10.  Transitional IPv6 host/router

   Transitional IPv6 host/router is a dual-stack host/router with
   IPv6-only WAN where IPv4 service support is provided by means of
   transition mechanism, IPv4aaS (IPv4-as-a-service)."

Dusan

Why is it important to mention WAN address family? Why WAN must be IPv6-only?
