With your approach you do not need this entire select. I pointed out to
you if you wanted to take the syscon approach.

This is also not needed if you do no take the syscon approach.

I think we still did not clarify why do you need this ID which in all
your examples increments by one. The description basically is a copy of
property name, so it does not explain anything.
