permits/denys what?  (a retorical query)
the point being that there is no practical difference btween 

	199.2.98.0/24 
and	192.0.0.0/24
or	128.0.0.0/24
or	191.255.255.0/24

these prefixes (and delegation points) are valid or potentially valid
in the routing system whereas

	192.0.2.0/24 
and	172.16.0.0/16
and	192.168.0.0/24
and	10.0.0.0/8

are not.
