OData Extension for Data Aggregation v4.0 - Comment on section 4 Cross-Joins and Aggregation

["Krause, Gerald" <gerald.krause@sap.com>]

Example 48 does not apply transformation addnested correctly:

• Instances in the result of a cross-join have a navigation property with a to-one cardinality for each entity set involved in the cross-join. Therefore, "Sales" is a single-valued navigation property of the instances in the resource collection
• The example applies addnested to âSalesâ
• The definition of addnested in section 3.4.3 limits the transformations that can be applied to single-valued navigation properties to identity, compute and addnested
• The example, however, applies the aggregate transformation
