font is explicitly _not_ derived from QObject. That's the whole point of 
value types. Value types, however, cannot exist as root objects. They 
need to be a property of something.

Well, yes, you need to declare the "person" property in C++ for now 
because you cannot have named value types. Once we get named value types 
(and some grammar fixes) you can do the following:

property person person {
     age {
         years: 1
         months: 0
     }
}

Simulation.onAdvanced: person.age.months++.
