A2.3 Value Constraint Determination for all Label Types

The table below lists all Label Types and summarizes VC-related modeling decisions. In almost all cases where a VC might have been used, it was decided to use a domain list instead. Only for ‘part number’ VC 1: {1, 2, …} was specified. For ‘integral number’ the Label Type name was thought to be clear enough (later to be implemented by a data type like ‘small integer’). By the way, Label Types ‘part number’ and ‘integral number’ cannot be united; ‘integral number’ identifies an amount of countable things, whereas ‘part number’ is a sequential label to distinguish parts by, so they are conceptually different.
