While it may accept it, you may find it doesn't really work the way it 
should :)  I had made the same assumption and discovered various problems. 
I ended up replacing it with:

-A RH-Firewall-1-INPUT -p udp -m udp --dport 32768:61000 -j ACCEPT
-A RH-Firewall-1-INPUT -p tcp -m tcp --dport 32768:61000 ! --syn -j ACCEPT

which is what ip6tables ships with.  You may need to adjust that port 
range depending on your apps.
