Hi,

Can you substantiate a bit on this statement?
How is it "random bits of information" when the specifications says
that it MUST be underscore?

As far as I can think of, the only thing that it will tell is that the
implementation is following this specification.
So, on the contrary; the more "degrees of freedom" that is given to the
implementation, the easier it would be to do fingerprinting.


Cheers,
 Andreas
