  34  * Note:
  35  *   There are four dissectors for the WAP protocol:
  36  *     WTLS
  37  *     WTP
  38  *     WSP
  39  *     WMLC
  40  *   Which of these are necessary is determined by the port number above.
  41  *   I.e. port 9200 (wap-wsp) indicates WSP data and possibly WMLC (depending on
  42  *   the WSP PDU).
  43  *   Port 9203 (wap-wsp-wtp-s), on the other hand, has WTLS, WTP, WSP and
  44  *   possibly WMLC data in that order in the packet.
  45  *
  46  *   Therefore the dissectors are chained as follows:
  47  *
  48  *   Port        Dissectors
  49  *   9200                     WSP  ->  WMLC
  50  *   9201            WTP  ->  WSP  ->  WMLC
  51  *   9202  WTLS  ->           WSP  ->  WMLC
  52  *   9203  WTLS  ->  WTP  ->  WSP  ->  WMLC
  53  *
  54  *   2948                     WSP  ->  WMLC (Push)
  55  *   2949  WTLS  ->           WSP  ->  WMLC (Push)
  56  *
  57  *   At present, only the unencrypted parts of WTLS can be analysed. Therefore
  58  *   the WTP and WSP dissectors are not called.
