All uses of DescriptionType should maybe be minOccurs="0" maxOccurs="unbounded" #62

mhoganRiff commented 4 years ago

There are 218 uses of DescriptionType in the B2MML standard. Of these 218 uses, 210 have the cardinality minOccurs="0" maxOccurs="unbounded"

The remaining eight uses of the DescriptionType declare the cardinality as minOccurs = 0. Since the default for "maxoccurs" is 1, this makes the Description element effectively an "optional" entity in these eight cases.

In B2MML 6.0, the cases are: TransChangeStatusType, OperationsMaterialBillType, OperationsMaterialBillItemType, OperationsSegmentType, ManufacturingBillType, ProductSegmentType, BatchEquipmentRequirementType, BatchParameterType

If the cardinality were changed to minOccurs="0" maxOccurs="unbounded", it would be a little more consistent, and it would not spoil backward compatibility. Existing, valid BatchML documents would remain valid with the new declarations.

This will be changed in the soon to be released. Changes made in: TransChangeStatusType, OperationsMaterialBillType, OperationsMaterialBillItemType, OperationsSegmentType, BatchEquipmentRequirementType, BatchParameterType, The following elements were removed in version 0700: ManufacturingBillType, ProductSegmentType because the Product Definition schema was removed.

Thank you Dennis
