Be sure you put it in correct place - ordered by unit address.

Sure, i will update it.

Why do you need them?

No, it's not required. I will remove.

reg is always a second property.

Sure, i will make it as second property.

Why do you need empty node? Usually there is no benefit and these should
be just part of parent.

Yeah, it should not be empty node. I will correct it.
