Check if validation of import can be improved
We validate metadata files in module publishCheck, but we do not have <generated>
metadata yet. So we can only ignore validation errors concerning this element. Therefore checks such as XML ID checks are not made, and false IDs not detected. We have to see, that we can validate correctly without having the <generated>
element. It is generated by TG-crud during #CREATE operation and given back from TG-crud.
