- PLI_QUALIFIERS: TS 102 223 qualifier values (Location Info, IMEI, NMR, Date/time, Timing Advance, Access Technology, etc.) - _command_details_name(): appends the qualifier description to PROVIDE LOCAL INFORMATION (type 0x26) in Command Details - decode_cat (FETCH) and decode_tr_command (TR) now use it, so both 'cat_command' and 'response_to' carry the qualifier (e.g. 'PROVIDE LOCAL INFORMATION — IMEI') tests: PLI qualifier cases (TR/FETCH, IMEI/location/date, non-PLI)
