Thanks for your reply.

It's not exclusive, it's disjunction. I don't want to depend on both of
them because they are huge. And some people would not like having orphan

Alright, then I'll just implement my solution. In any case, I like it. Just
wanted to hear others opinion.

Thanks again and best regards,
