There are some properties that are missing from Appendices like "fcs/throttle-cmd-norm".
A description for all these properties is helpful (and maybe an example for each one :) ) and for each attribute + all possible values.
e.g.: <set name="ap/altitude_setpoint" action="FG_EXP" value="1000" tc="10"> or <set name="fcs/throttle-cmd-norm" value="1.0" action="FG_RAMP" tc="0.5"> or <set name="fcs/mixture-cmd-norm" value="1.00" action="FG_RAMP" tc="0.5"></set></set></set>
