   I would like to suggest that the 2 octets lengths be changed to support
   the 1-2-5 octet length conventions used elsewhere in the draft.
   in addition to being more consistant it would allow us to save 
   a some bytes when building up multiple ticket packets..
   
   the downside is can make packet processing a bit more complex, but 
   all implementations of PGP will have code to handle the 1-2-5 lengths
   anyways.
   
   any comments?
   
It's an excellent suggestion. Until a draft or so ago, the total length of
all subpackets was a two-octet length, so there was no reason for the
fields here to be longer. Now that the subpacket region can be 4 gig in
size, this should be expanded. Future generations will thank us.
