I see.
I thought it was:
  [foo, bar, baz, bat, [[obj1, loc1], [obj2, loc2]]]

but I understand the CDDL better now.

The original capture was, to repeat:

   [9, 3591865773, h'2607F0B0000F000200000000000005F7', 120000,
     [
       ["AN_join_registrar", 5, 1, "EST-TLS"],
       [103, h'2607F0B0000F000200000000000005F7', 6, 80]
     ]
   ]

So, if there were two objectives, it would be:

   [9, 3591865773, h'2607F0B0000F000200000000000005F7', 120000,
     [
       ["AN_join_registrar", 5, 1, "EST-TLS"],
       [103, h'2607F0B0000F000200000000000005F7', 6, 80]
     ],
     [
       ["AN_more_funr", 5, 1, "EST-TLS"],
       [104, h'2607F0B0', 6, 80]
     ]
   ]
