When I originally submitted the patches for DHCPv6 I thought that using 
the host name for specifying hosts with fixed IPv6 addresses would 
work.  Lots of testing proved that to be a foolish assumption.  The only 
thing that works is to specify the ID (Client ID).  This has been 
testing with DUID-LLT, DUID-LL, and DUID-UUID.

One of the most difficult parts in this was getting the patterns in the 
schemas correct for the various types of DUID.  I think I have tested 
them sufficiently but ???  One of the more difficult things was to 
handle bytes where the leading zero is suppressed.
