Question about IPng addressing

[Mike Crawfurd]

Dear people,

I'm researching IPng, and read various documents, rfc's and white
papers. Today I found something that confused me. The pages from sun's
playground,
http://playground.sun.com/pub/ipng/html/INET-IPng-Paper.html#CH7
indicated that the prefix for Provider-Based Unicast Address is 010 and
100 is reserved for Neutral-Interconnect-Based Unicast Addresses.

However in the internet-draft draft-ietf-ipngwg-addr-arch-v2-05.txt
these two are not in the reservation specs, although it is a more
current document.

Are the two mentioned prefixes discarded in the new specs ? And if so,
what's the reason behind this decision ?

Thanks for all your Help,

Mike Crawfurd.
