> Currently NavigationPropertyPath expressions must end with a navigation property name, and PropertyPath expressions must end with the name of a structural property.
> On the other hand annotations add "virtual (navigation)properties", so a NavigationPropertyPath expression could as well end with an annotation of type Edm.EntityType or any concrete entity type (or a collection of these), and a PropertyPath expression could end with an annotation of types Edm.ComplexType, Edm.PrimitiveType, or a concrete primitive, enumeration, or complex type, or a type definition.
> An example for  "virtual navigation properties" is given in https://tools.oasis-open.org/issues/browse/ODATA-278 . The aim was that we can use  "virtual navigation properties" (and  "virtual properties") also as a NavigationPropertyPath (and as a PropertyPath ).  Currently  the expressions
>            <PropertyValue Property="NavigationPath" NavigationPropertyPath="@ACR.Supplier" /> and 
>            <PropertyValue Property="NavigationPath" NavigationPropertyPath="@ACR.PurchaseOrders" />
> in the example are invalid, because the  NavigationPropertyPath expressions must end with a navigation property name.
