    I strongly support this work.
    IMO we need the same work to be done with OSPFv2. Shall it be part 
of this document or work on its own is a separate question.
    Number of I-Ds submitted against OSPFv2 shows that this version of 
the protocol is still being actively worked on and in medium term many 
extensions will have to be simultaneously proposed for v2 and v3. Having 
Extendable LSAs in both protocol versions would greatly simplify 
standardization and development of such extensions.

    I have a few notes on current draft but I do not want to hijack this 
thread for technical discussion and better send another email.

Thanks,

Anton
