Right. Assuming that your explanation is correct, that makes sense.
In that case, a Component is essentially the QML equivalent of a
class, defining an object template but not instantiating it. I'll have to
play
around with this to see exactly how it works.

Does an Item, conversely, both define an object template and
instantiate it, so that an Item can be used anywhere a Component
can be used ?
