ODATA-24 simplified relationships by moving association information into navigation properties.
In applying the changes for ODATA-24, two references in [Core], Part I were missed:
Section 3, Data Model talks about "association types" as being structural types, and section 10.4.1.1, "Entity Set Path Expressions" talks about deducing entitysets by backing association sets (needs to be updated to describe navigationpropertybindings).
