Two more comments.



4.) I'd also use sub-type value of (2) for IMSI. Just to align with the
sub-types defined for MN Id defined for ICMP. I suspect there are some
implementations already using sub-type (2). Please see the other thread.


5.) For each of the sub-types, we need text including examples and some
explanation on how they are used.
