  !!! DSMCC INT/UNT descriptors are in a private tag space !!!

  EN 301 192:
  Descriptors from the DVB SI range (0x40 - 0x7F) shall have their standard
  semantics as defined in EN 300 468 [2].
  Equally MPEG descriptors in the range 0x00 - 0x3F can not be used in the
  INT.  Note that descriptor tags from 0x00 to 0x3F share a common descriptor
  name space with UNT descriptors (see TS 102 006 [19]).
  All descriptors may appear more than once in the INT sub-table at the
  locations indicated above. In the case of name_descriptors multiple
  occurrences require different ISO 639 language codes.
