As a recap, the problem we're working to fix is the text change that was 
introduced in "draft-...05", which was giving "addresses" the role of 
tunnel endpoints.

I am trying to bring the definition in line with the architectural 
concepts/definition, and restore consistency:

- addresses are identifiers of nodes/interfaces
- nodes/interfaces are endpoints of ptop links.

So, the text lastly suggested restores the role of identifiers to 
"addresses".

Please see further in line:

This can be resolved by:

IPv6-over-IPv4 tunneling where the IPv4 tunnel endpoint address(es)
are determined by configuration information on tunnel endpoints. All
tunnels are assumed to be bidirectional. At the IPv6 layer the tunnel 
provides a (virtual) point-to-point link, using a pair of an IPv4 
address of each of the endpoints as lower layer addresses.

or,

IPv6-over-IPv4 tunneling where the IPv4 tunnel endpoint address(es)
are determined by configuration information on tunnel endpoints. All
tunnels are assumed to be bidirectional. At the IPv6 layer the tunnel 
provides a (virtual) point-to-point link, using a pair of IPv4 addresses 
of each of the endpoints as lower layer addresses.
