Question about 223/8

[Jack Bates <jbates () brightok net>]

I'm confused about the argument I believe that went on not too long ago 
concerning 223/8. What documentation governs how IANA allocates address 
space, including special use space?

The reason I ask is that I was perusing RFC 3330 and noted that it 
specifically stated that the basis for the reservation of 
223.255.255.0/24 no longer applied and that the block was subject to 
future allocation to a RIR. Yet there was an argument about it.
