Your example is an aircraft in the cruise at FL350, so it's to be expected that the Vrate will be 0  :-)  It's certainly displayed for aircraft in the climb and descent ...

Airspeed is rarely transmitted as an ADS-B parameter, and I've never seen it in the XML output.

Squawk should obviously be there, but isn't - I believe that's due to be rectified in a future release (but it's still broken in V3.01).
