I'm not sure it's just a matter of taste. It feels wrong to me to have two
element declarations for element part, one global and one local, when all
the part elements are the same. It gives the same answers as far as
validation of instances is concerned, but it seems a messier component
model, which could give you a messier translation into classes when you do
data binding, for example (I don't know if that's actually the case).
