 As expected, only the two state-derivative equations remain,
 as if you had manually eliminated as many variables as possible from the equations.
+Some observed variables are not expanded unless `full_equations` is used.
 As mentioned above, the hierarchical structure is preserved though. So the
 initial state and the parameter values can be specified accordingly when
 building the `ODEProblem`:
