PropertyHandle :: SetSortKey - Store sort key value to instance
The passed key value is stored to the component attributes of the selected sort key in the instance. When passing an empty instance the key is stored in the selected instance of the property handle. When no instance is passed or selected or when no sort key is defined for the structure the function returns an error (YES).
Return value: Success ( logical )

Instances do have the type of the referenced property handle (collection type). The instance contains a pointer to a properly structured instance area.
You can use the !-operator or the GetData() function to check whether the instance refers to data or not.
