I would say:
If the numbers are aligned you don't need separate
mapping tables for IPv4 and IPv6.
The idea is that you map an NSLP ID, i.e. a an identifier
for a specific signaling application like QoS NSLP or
NAT/FW NSLP to an RAO value as demultiplexer.
In this case you would only
need one mapping table and not two different tables for
v4/v6. Technically you can have separate v4/v6 RAO tables,
but using only one would be easier to implement etc.
