  46  * Note:
  47  *   There are four dissectors for the WAP protocol:
  48  *     WTLS
  49  *     WTP
  50  *     WSP
  51  *     WMLC
  52  *   Which of these are necessary is determined by the port number above.
  53  *   I.e. port 9200 (wap-wsp) indicates WSP data and possibly WMLC (depending on
  54  *   the WSP PDU).
  55  *   Port 9203 (wap-wsp-wtp-s), on the other hand, has WTLS, WTP, WSP and
  56  *   possibly WMLC data in that order in the packet.
  57  *
  58  *   Therefore the dissectors are chained as follows:
  59  *
  60  *   Port        Dissectors
  61  *   9200                     WSP  ->  WMLC
  62  *   9201            WTP  ->  WSP  ->  WMLC
  63  *   9202  WTLS  ->           WSP  ->  WMLC
  64  *   9203  WTLS  ->  WTP  ->  WSP  ->  WMLC
  65  *
  66  *   2948                     WSP  ->  WMLC (Push)
  67  *   2949  WTLS  ->           WSP  ->  WMLC (Push)
  68  *
  69  *   At present, only the unencrypted parts of WTLS can be analysed. Therefore
  70  *   the WTP and WSP dissectors are not called.
