Wouldn't expect IPv4/v6 to be multiplexed on a single template;
each should have its own. ie., on a Cisco:

# sho run | inc flow-export
ip flow-export source Loopback286
ip flow-export version 9
ip flow-export destination x.x.x.x yyyy
ipv6 flow-export source Loopback286
ipv6 flow-export destination x.x.x.x yyyy

# sho ip flow export template
   ...
   Total number of Templates added = 2
   Total active Templates = 2
   Flow Templates active = 2
   Flow Templates added = 2
   ...

The hack to introduce sampling information in NetFlow v5, we
can say a-posteriori it was quite successful. Remains to see
who has interest in pushing the next one ...
