Summary0007364: Redundant constraint for DataInstanceUse
DescriptionCurrently the DataInstanceUse clause contains a constraint restricting the use of argument and reduction lists:

Either argument list or reduction list provided
Either one of the 'argument' list or 'reduction' list or none of them shall be provided.

A similar constraint is already defined under DataUse (super-class of DataInstanceUse):

Occurrence of 'argument' and 'reduction'
Both, 'argument' and 'reduction', may be provided only in case of a 'FunctionCall'.

Since DataInstanceUse is a sub-class of DataUse, all constraints that are applicable to DataUse already apply to DataInstanceUse. In addition, since the only difference between these constraints is the special case for FunctionUse in the constraint for DataUse, and a DataInstanceUse already excludes that part of the constraint, the constraint for DataInstance use is redundant.

The proposal is to remove the constraint for DataInstanceUse.

The constraint in DataInstanceUse is removed. The constraint in DataUse is refined to

Occurrence of 'argument' and 'reduction'
Only in case of a ‘FunctionCall' both the 'argument' list and the ‘reduction' list may be provided, otherwise either the 'argument' list, the ’reduction' list, or none of them shall be provided.

This also applies to FormalParameterUse and VariableUse.
