But that major implementation had to revert to sending the entire
LSA (header + body) because another major implementation did not
like it :).

Have gone thru enought pain on this subject and would prefer not
having to do yet another revision. As far as efficiency and memory
is concerned, I wouldn't worry too much about it for this particular
case.
