      Introduce "primitive types" Edm.Property and Edm.NavigationProperty that can only be used in the Type attribute of a Term or a property of a complex type that is used as the type of a term.

      Add new attributes PropertyPath and NavigationPropertyPath to Annotation and PropertyValue with the same syntax as the Path attribute:

      <Annotation Term="Temporal.ApplicationPeriod">
      <PropertyValue Property="StartPeriod" PropertyPath="bus_start" />
      <PropertyValue Property="EndPeriod" PropertyPath="bus_end" />
      </Annotation>

      <Annotation Term="RelatedStuff" NavigationPropertyPath="Suppliers" />

      <Annotation Term="LookOverThere">
      <PropertyPath>SupplierName</PropertyPath>
      </Annotation>

      Also introduce elements for element notation of annotation values.

      Description

      The Edm.String data type can be used to define a type annotation property when the property will hold the name of some other property. A more specific data type could be added to OData for this purpose.

      In the OData Extension for Temporal Data we suggested this annotation:

      <Annotation Term="Temporal.ApplicationPeriod">
      <PropertyValue Property="StartPeriod" String="bus_start" />
      <PropertyValue Property="EndPeriod" String="bus_end" />
      </Annotation>

      Instead of declaring StartPeriod and EndPeriod to be of type String, we could declare them to be of type PropertyName.
