> Today navigation properties must be direct children of the entity. We should support navigation properties being defined on properties grouped into a complex type. For example:
> <ComplexType Name="Address">
> <Property Name="Street" Type="Edm.String" />
> <NavigationProperty Name="City" Type="MyModel.City" />
> <NavigationProperty Name="Region" Type="MyModel.Region" />
> <NavigationProperty Name="Country" Type="MyModel.Country" />
> </ComplexType>
> If a type <Person> has an Address, then you could express the navigation property binding as:
> <EntitySet Name="People" Type="Person">
> <NavigationPropertyBinding Path="Address/City" EntitySet="Cities"/>
> <NavigationPropertyBinding Path="Address/Region" EntitySet="Regions"/>
> <NavigationPropertyBinding Path="Address/Country" EntitySet="Countries"/>
> </EntitySet>
