I'm sure this is an unadvisable string to pull on, BUT.


1. RFC2373 had a RFC2119 reference.
2. RFC2373 has the text "The format prefixes 001 through 111, except for 
Multicast Addresses (1111 1111), are all required to have to have 64-bit 
interface identifiers..."
3. For some reason unknown to me; In draft-ietf-ipngwg-addr-arch-v3-03 
the reference to RFC2119 was dropped.
3. The text "For all unicast addresses, except those that start with 
binary value 000, Interface IDs are required to be 64 bits long..." is 
introduced in draft-ietf-ipngwg-addr-arch-v3-06, this is essentially 
equivalent to the text in #2
4. RFC3513 and RFC4291 have NO reference to to RFC2119 and the text "For 
all unicast addresses, except those that start with binary value 000, 
Interface IDs are required to be 64 bits long..."
