Define rules for the target of an annotation that supports implicit casting of relationships

When mapping properties of a term the target of the mapping MUST be of the type specified in the term definition or a derived type of the specified type, or annotated with the specified type or a subtype of the specified type. Example vocabulary: <Schema Namespace="vCard"> <Term Name="Contact" Type="vCard.ContactType" AppliesTo="EntityType,ComplexType" /> <ComplexType Name="ContactType"> <Property Name="PhoneNumbers" Type="Collection(vCard.PhoneNumberType)" /> ... </ComplexType> <Term Name="PhoneNumber" Type="vCard.PhoneNumberType" AppliesTo="EntityType,ComplexType" /> <ComplexType Name="PhoneNumberType"> <Property Name="Number" Type="String"/> ... </ComplexType> </Schema> Example service with annotations: <Schema Namespace="SomeService"> <EntityType Name="Customer"> ... <NavigationProperty Name="Phones" Type="Collection(SomeService.Phone)"/> ... <Annotation Term="vCard.Contact"> <Record> <PropertyValue Property="PhoneNumbers" Path="Phones/vCard.PhoneNumber#work" /> </Record> </Annotation> </EntityType> <EntityType Name="Phone"> ... <Property Name="work_phone_number" Type="String"/> ... <Annotation Term="vCard.PhoneNumber" Qualifier="work"> <Record> <PropertyValue Property="Number" Path="work_phone_number" /> </Record> </Annotation> </EntityType> </Schema> Accepted: https://www.oasis-open.org/committees/download.php/48097/odata-meeting-23_on-20130130_31-F2F-minutes.html#odata-108
