Oris it even more complicated than that ?
I never thought about that possibility - it is an interesting idea,
and it solves the logical problem (though there is still a need to
ensure that if child property is set, that the user won't be able
to also set a parent property - which is probably implementable by
using triggers).
Though I would prefer, if it is possible, something much simpler,
because there are only about 10 properties and 2 'composite'
properties - it would probably be an overkill to create a tree for
such a small table if a simpler solution exists.
