1. Example WebSocket payload:

       {
       "00000002": { "vr" : "UI", [ "1.2.840.10008.5.1.4.34.​6.​4" ] },
       "00000100": { "vr" : "US", [ 256 ] },
       "00000110": { "vr" : "US", [ 23 ] },
       "00000800": { "vr" : "US", [ 0 ] },
       "00001000": { "vr" : "UI", [ "1.2.840.10008.5.1.4.34.​6.​4.2.3.44.22231" ] },
       "00001001": { "vr" : "US", [ 1 ] },
       "00741238": { "vr" : "CS", [ "SCHEDULED" ] },
       "00744041": { "vr" : "CS", [ "READY" ] }
       }

2. The WebSocket protocol does not allow content negotiation so it is not possible to support both XML and JSON encoding of Event Report messages without extending the protocol.
