I caught up on the back and forth on IDNA.  The incompatibilities between 
IDN2003 and IDN2008 are limited to the encoding of two uncommon 
characters, which the IDNA group think is not a big deal, hence their 
decision not to change the xn-- prefix.  Really, we should change the 
references to the current standard.
