org.apache.olingo.odata2.api.ep.EntityProviderReadProperties
The {@link EntityProviderReadProperties} contains all necessary settingsto read an entity with the {@link EntityProvider}.

The main settings are
- the mergeSemantic
- the callback for inlined navigation properties
- the type mappings
- and validatingFacets

        (EdmNavigationProperty) eia.getEntityType().getProperty(navigationPropertyName);

    // validations
    boolean isFeed = isInlineFeedValidated(reader, eia, atomLinkType, navigationPropertyName);
