   The NBPEntity structure is used to manipulate NBP names without regard
   to issues of what kind of "special" characters are in the name.
   
   When stored as an address in an NBPAddress or DDPNBPAddress, they are 
   stored as a character string, which is currently just ASCII, but in the
   future may be UniChar, or some other internationalizable scripting set.
   The string following an NBPAddress or DDPNBPAddress is intended to be
   suitable for showing to users, whereas NBPEntity is not.
   WARNING: NBPAddress and DDPNBPAddress structures do not "know" the length
   of the address.  That must have been obtained as part of a Lookup or
   ResolveAddress call.
