It was documented a year after its delegation in a now expired draft
by Richard Troll.  There is an RFC that describes problems with auto
configuration using this prefix.  There is also a current draft in/from
zeroconf that talks about this prefix.  I've had a draft that describes
this prefix killed a couple of times by the IESG/IAB.  
The prefix was originally delegated after the LA IETF. You'll find a 
brief mention of the action on the last page fo the DHCP wg minutes.
