That's really different from what I thought. Maybe I'm getting my
terms messed up, but I wouldn't think the verifier would pay any
attention at all to this flag, unless the verifier itself were in a
position to create a new cert, and that was the operation in question.
Having the flag set in the middle of a chain would be essentially
meaningless to the verifier -- all it does is go through the chain and
make sure it is verifiable all the way through. The bit really does
not mean "delegate"! It has no meaning at all as far as verification
of the cert, or delegation of authority. That's what you wanted,
wasn't it :-)
It just means that the holder of this particular cert is able to go
to the signer of the cert to get a new cert with reduced authority,
in whatever terms the signer of the cert understands.
