The packet-etsi_card_app_toolkit.c file doesn't dissect that tag (0x16). That might have been an unintentional omission or perhaps the author just had no way to test it. Whatever the reason, if you want it to be dissected, you should submit a Wireshark bug report asking for it to be dissected. Note that there appear to be others not handled too, among them these candidates:

Note that just because a bug report is filed doesn't mean support will be added. By far the best way for something to be supported is if you can write it yourself and submit a patch.
