Constraint DataInstanceOrArgumentsOrItemsInDataElementUse incorrect
Given:
```
Structure msg (
Integer id,
Data data
)
Collection Data of msg
```
and
```
Data d2 [
new msg(id = 1)
]
Data d2a [
d2[1] //TODO: constraint is messed up
]
```
A constraint violation is raised in d2\[1\] "If a 'dataElement' is not specified, or if the 'dataElement' is resolved to a 'StructuredDataType' or a 'CollectionDataType', either a non-empty 'argument' set or a non-empty 'item' set shall be specified"
The implementation of the constraint is:
```
inv DataInstanceOrArgumentsOrItemsInDataElementUse ('If a \'dataElement\' is not specified, or if the \'dataElement\' is resolved to a \'StructuredDataType\' or a \'CollectionDataType\', either a non-empty \'argument\' set or a non-empty \'item\' set shall be specified.' + self.toString()):
not (self.dataElement.oclIsUndefined() and self.argument->isEmpty() and self.item->isEmpty())
and (self.dataElement.oclIsKindOf(StructuredDataInstance)
or not (self.resolveDataType().oclIsKindOf(StructuredDataType)
and self.argument->isEmpty()))
and (self.dataElement.oclIsKindOf(CollectionDataInstance)
or not (self.resolveDataType().oclIsKindOf(CollectionDataType)
and self.item->isEmpty()))
```
