> With ODATA-960 we added absolute paths to the Path syntax, which allows referencing properties of a singleton, e.g.
> <Annotation Term="Display.visible" Path="/this.container/Settings/FeatureXxxIsAvailable" />
> A logical extension is allowing key expressions to reference entities and their properties within an entity set:
> <Annotation Term="Display.visible" Path="/this.container/SettingsCollection('FeatureXxx')/IsAvailable" />
> In addition to literal values the key values can be provided using path expressions. This enables (a third party) to address content where the service author forgot to define a navigation path:
> <Annotation Term="Display.title" Path="/this.container/Products(ID=ProductID)/Name" />
