Now its seems that there are more problems than to have correct UoS/UoM. I
suggest that clever use of inheritance can be solution, f.e. create
templates for invoice and invoice line which will have 99% of functionality
and inherit them to create  new objects for extending, changing
customer/supplier invoices/invoice line objects. If we choose to put
all differences on one place it can be to complicate in the future
to understand all these complex situations, dividing to smallest parts
gives opportunity for every country to adapt accounting for its own needs.
