RFC 4193 addresses are commonly referred to, both in and out of the IPv6 
WG, as ULAs.  Perhaps the acronym isn't clear, since it doesn't actually 
appear in the RFC, but it is arguably correct.

That depends if the intent of 2006-2 was to address hosts that could be 
accessed from outside the AS or not.  If no, then 2006-2 should be 
killed and/or replaced with a policy telling people to use RFC 4193 
ULAs.
