You might want to have a look at section 4 and 5 of http://www.ietf.org/internet-drafts/draft-ietf-isis-auto-encap-02.txt too.

Auto-encap would certainly be more idiot proof if someway could be built into isis-ipv6 to prevent an IPv6 only router from forming an adjacency with an IPv4 only router, in line with what the ITU-T did in G.7712.
