Packet redirect:fixed meta data ID assignment,into IANA part?

   In protocol draft version 8,the redirect packet is transimitted to CE 
using an redirect TLV encapsulation which has two main 
constructors:meta-data ILVs which encapsulate the associated meta 
informations with the packet such as output id,input port id etc and 
Redirect data TLV which encapsulate the real packet.According to meta 
ILV,the identifier of meta data is important,I look through issue32,it 
seems that on paris wg meeting we have come to an consensus that static 
metadata assignment will be used, with metadata transcoding as necessary.To 
make static meta data assignment,i think we should put meta data ID 
assignment to IANA consideration,if that is the case,then we need some 
inital meta data definitions,are there any mistakes,thanks.
Yours,Fenggen
