   I notice that Section 4 calls for TLV:
] 
] 4. Proposed IPv6 Extension Header format
] 
]  This document proposes that all IPv6 extension headers be encoded in
]  a consistent TLV format so that it is possible for nodes to skip over
]  unknown extension headers and continue to further process the header
]  chain.

   But I don't see the equivalent of Section 4.2 of RFC 2460, specifying
the TLV format.

   What am I missing?
