Handling of light hadron decays
I think the tool does not take into account some recent rules regarding the decays of light hadrons:
e.g. this commit lhcb-datapkg/Gen/DecFiles!356 (ec9091b4) introduces the rule that an event type of the form 39XXXX3X
is needed to generate the decays of the \eta
meson while 39XXXX0X
-39XXXX2X
are reserved for the \phi
decays.
It could be that other similar cases are not known to the tool, as well.
