good. thanks for pointing that out.

a.  perhaps this could be made clearer in the next version?
    the current draft implies more than once that these addresses 
    could be used for testing or test networks, which is pretty
    close to saying they can be used for private operational networks.
    test networks sometimes evolve into operational networks if the
    test is successful.

b.  I wonder if 3FFE:FFF0:: addresses make good examples, since they 
    will "look different" than addresses in typical use (outside of
    the 6bone).  Also, might it be useful to have multiple example 
    prefixes so that in examples citing addresses from different parts 
    of the net the different prefixes would be easily distinguishable?
