I think this is the only reasonable interpretation. The codes inside
the types do not have such ordering that it would be usefull to say
send all types 1, 2, 3 with codes 2, 3 to this SA. On the other hand
I think most used features will be where tstart == tend, and cstart
and cend specify the part of that ICMP type, or where the tstart and
tend have range and cstart = 0, and cend = 255, i.e. all codes for
those types.
